A baseball player leads off the game and hits a long home run. The ball leaves the bat

at an angle of 30.0o
from the horizontal with a velocity of 40.0 m/s. How far will it
travel in the air?

Working out please

Vo = 40m/s[30o]

Xo = 40*cos30 = 34.64 m/s.
Yo = 40*sin30 = 20 m/s.

Y = Yo + g*Tr = 0
Tr = -20/-9.8 = 2.04 s. = Rise time.

Y^2 = Yo^2 + 2g*h = 0
h = -(Yo^2)/2g = -(20^2)/-19.6=20.4 m.

h = 0.5g*t^2 = 20.4
4.9t^2 = 20.4
t^2 = 4.16
t = 2.04 s. = Fall time(Tf).

Range = Xo * (Tr+Tf)=34.64m/s * 4.08s. =
141.3 m.

Kate I think Your response is a little late

Bruh my teacher really had the same question this page has that was made in 2015

Well, if the baseball player hits the ball and it leaves the bat at an angle of 30.0 degrees, it sounds like the ball is really trying to take off and fly away!

As for how far it will travel in the air, we can use some good old physics to figure it out.

First, we need to break down the velocity of the ball into its vertical and horizontal components. The horizontal component will determine how far the ball travels, while the vertical component will determine how high it goes before coming back down to earth.

The vertical component can be found by multiplying the initial velocity (40.0 m/s) by the sine of the launch angle (30.0 degrees). So, the vertical component is 40.0 m/s * sin(30.0 degrees) = 20.0 m/s.

Now, the horizontal component can be found by multiplying the initial velocity (40.0 m/s) by the cosine of the launch angle (30.0 degrees). So, the horizontal component is 40.0 m/s * cos(30.0 degrees) = 34.64 m/s.

Since the ball will travel in the air until it hits the ground, we are only concerned with the horizontal distance. So, to determine how far it will travel, we can use the horizontal component of velocity (34.64 m/s) and the total time the ball is in the air.

The time it takes for the ball to hit the ground can be found using the equation: time = (2 * vertical component of velocity) / gravitational acceleration. Since we're on Earth, the gravitational acceleration is approximately 9.8 m/s^2.

So, the time it takes for the ball to hit the ground is:
time = (2 * 20.0 m/s) / 9.8 m/s^2 ≈ 4.08 seconds.

Now that we know the time, we can calculate the distance the ball will travel horizontally by multiplying the horizontal component of velocity (34.64 m/s) by the time (4.08 seconds).

So, the distance the ball will travel in the air is approximately:
distance = 34.64 m/s * 4.08 seconds ≈ 141.43 meters.

Therefore, the ball will travel about 141.43 meters in the air before it comes back down to Earth. But hey, who needs math when you can just watch it on TV and cheer for your favorite team?

To find out how far the baseball will travel in the air, we can use the kinematic equations of motion. Specifically, we'll use the equation for the horizontal distance traveled:

Horizontal distance = initial velocity * time * cosine(angle)

Given:
- Initial velocity (magnitude of the velocity) = 40.0 m/s
- Angle = 30.0 degrees

First, we need to convert the angle from degrees to radians because trigonometric functions use radians. We can use the following conversion formula:

angle in radians = angle in degrees * (π/180)

Plugging in the values:
angle in radians = 30.0 degrees * (π/180) = 0.523 radians

Now we can calculate the horizontal distance traveled. However, we need to find the time of flight first. Since there is no upward or downward acceleration in horizontal motion, we can consider the time of flight as the same for both vertical and horizontal motion.

The time of flight (t) can be calculated using the equation for vertical motion:

Final velocity (vertical) = Initial velocity (vertical) + acceleration (vertical) * time
0 = 0 + (-9.8 m/s^2) * time

Solving for time:
time = 0 / (-9.8 m/s^2)
time = 0 seconds

Since time is 0 seconds, the vertical component of the motion finishes instantly. Therefore, the horizontal distance traveled is simply the horizontal component of the velocity multiplied by the total time of flight, which is 0 seconds.

Horizontal distance = initial velocity * 0 * cosine(angle)
Horizontal distance = 40.0 m/s * 0 * cos(0.523 radians)
Horizontal distance = 0 meters

Therefore, the baseball will travel 0 meters in the air.
