A ball is dropped from the top of a 53.0m high cliff. At the same time, a carefully aimed stone is thrown straight up from the bottom of the cliff with a speed of 25.0m/s The stone and ball collide part way up.

How far above the base of the cliff does this happen in meters?

Write equations for the heights of each ball vs time and set them equal. Solve the resulting equation for time. Then compute the vertical height at that time.

y1 = 53.0 - 4.9 t^2
y2 = 25 t - 4.9 t^2

y2 - y1 = 0 = 25 t - 53
t = 53/25 s = 2.12 s
y1 = 31.0 m

Well, that's quite an interesting situation! So we have a ball and a stone both trying to defy gravity. I guess they got tired of falling and wanted to have a little mid-air rendezvous.

Now, let's calculate how far above the base of the cliff they collide. Since we know the initial velocity of the stone is 25.0 m/s and the ball is dropped, we can determine how long it takes for both of them to reach their meeting point.

Let's assume that the collision happens after time 't'. During this time, the stone will rise and the ball will fall. The distance traveled by the stone 'd1' will be given by: d1 = (1/2)gt^2 - where 'g' is the acceleration due to gravity.

Now, to figure out the distance traveled by the ball 'd2', we use the formula: d2 = 53.0 m - (1/2)gt^2.

Since we want to find the distance when they collide, we can set d1 equal to d2 and solve for 't'. Are you ready for the math circus to begin? Here we go!

(1/2)gt^2 = 53.0 m - (1/2)gt^2

Simplifying this equation, we get:

gt^2 = 2(53.0 m)

Now we can solve for 't' by dividing both sides by 'g':

t^2 = (2 * 53.0 m) / g

t = √((2 * 53.0 m) / g)

Now all we need to do is substitute the value of 'g' (approx. 9.8 m/s^2) into the equation and calculate 't'. Once we have 't', we can find the distance above the base. I hope you enjoy this gravity-defying mathematical circus!

*tada* According to my calculations, the distance above the base where the ball and stone collide is approximately [insert answer here] meters.

To find the distance above the base of the cliff where the stone and ball collide, we need to find the time it takes for each object to reach that height.

Let's first analyze the motion of the ball:
1. We know the height of the cliff is 53.0m.
2. The ball is dropped, so its initial velocity, u, is 0 m/s.
3. The acceleration due to gravity, a, is approximately 9.8 m/s^2 (taking direction as positive downwards).
4. We need to find the time, t, taken by the ball to reach the collision point.

Using the kinematic equation: s = ut + (1/2)at^2, we can solve for t:
53.0 = 0t + (1/2)(9.8)t^2
53.0 = 4.9t^2
t^2 = 53.0 / 4.9
t^2 ≈ 10.81632653

Taking the positive square root, we find:
t ≈ √10.81632653
t ≈ 3.29 seconds (rounded to two decimal places)

Now, let's analyze the motion of the stone:
1. The initial velocity, u, of the stone is 25.0 m/s upward.
2. The acceleration due to gravity, a, is approximately 9.8 m/s^2 (taking direction as positive downwards).
3. We need to find the time, t, taken by the stone to reach the collision point.

Using the kinematic equation: v = u + at, we can solve for t:
0 = 25.0 - 9.8t
9.8t = 25.0
t ≈ 25.0 / 9.8
t ≈ 2.55 seconds (rounded to two decimal places)

Since the stone reaches the collision point before the ball, the distance above the base of the cliff where the stone and ball collide is determined by the stone. Therefore, the collision occurs approximately 2.55 seconds after the stone was thrown.

To find how high above the base of the cliff this happens, we need to calculate the stone's height at time t = 2.55 seconds:
Using the formula: s = ut + (1/2)at^2, we have:
s = 25.0(2.55) + (1/2)(-9.8)(2.55)^2
s ≈ 63.85 meters (rounded to two decimal places)

Therefore, the stone and ball collide approximately 63.85 meters above the base of the cliff.

To determine the position where the stone and ball collide, we can first calculate the time when the two objects meet. This can be done by finding the time it takes for each object to reach that position.

First, let's find the time it takes for the ball to fall from the top of the cliff to the collision point:

Since the ball is dropped, we can use the equation of motion for free fall:

h = (1/2) * g * t^2

where:
h = height of the cliff (53.0 m)
g = acceleration due to gravity (approximately 9.8 m/s^2)
t = time

Rearranging the equation to solve for time:

t = sqrt((2h) / g)

Plugging in the values:

t = sqrt((2 * 53.0) / 9.8)
t ≈ 3.22 seconds

Therefore, the ball takes approximately 3.22 seconds to fall from the top of the cliff to the collision point.

Now, let's find the time it takes for the stone to reach the collision point:

Since the stone is thrown upwards, we can use the equation for vertical motion:

v = u + gt

where:
v = final velocity (0 m/s at the topmost position)
u = initial velocity (25.0 m/s)
g = acceleration due to gravity (approximately -9.8 m/s^2)
t = time

Rearranging the equation to solve for time:

t = (v - u) / g

Plugging in the values:

t = (0 - 25.0) / -9.8
t ≈ 2.55 seconds

Therefore, the stone takes approximately 2.55 seconds to reach the collision point.

To find the position where the stone and ball collide, we can use the equation:

d = u1 * t1 + (1/2) * a1 * t1^2

where:
d = distance traveled
u1 = initial velocity of the stone (25.0 m/s)
t1 = time taken by the stone to reach the collision point (2.55 s)
a1 = acceleration due to gravity (-9.8 m/s^2)

Plugging in the values:

d = 25.0 * 2.55 + (1/2) * (-9.8) * (2.55)^2
d ≈ 32.4 meters

Therefore, the stone and ball collide approximately 32.4 meters above the base of the cliff.
