1) If the ball has mass 0.15 kg and the boy's arm moved through 1.5 m as he threw the ball, then what average force did he exert on the ball?
Please show it step by step along with the equation to users

a. Find the speed required to throw a ball straight up and have it return 6 seconds later. Neglect air resistance. b. How high does the ball go? Please Help!! Thanks!! :)
A student throws a baseball at a large gong 73 m away and hears the sound of the gong 1.7744 s later. The speed of sound in air is 330 m/s. What was the average speed of the base- ball on its way to the gong? (For simplicity, assume its trajectory to be a
a tennis ball is thrown straight up with an initial velocity of 22.5 m/s. it is caught at the same distance above the ground. a). how long does it take to reach its maximum height? b). how high does the ball rise? c). at what speed does it hit the ground?
a ball is thrown straight upward and returns to the thrower's hand after 3.00s in the air. A second ball is thrown at an angle of 30.0 deg with the horizontal. At what speed must the second ball be thrown so that it reached the same height as the one
A ball is thrown straight up into the air. At each of the following instants, is the magnitude of the ball's acceleration greater than g, equal to g, less than g, or zero? Air resistance may be neglected. A) just after leaving your hand? B) at the very top
A ball is shot straight up into the air with initial velocity of 47 ft/sec. Assuming that the air resistance can be ignored, how high does it go?
A ball of mass 0.4 kg, initially at rest, is kicked directly toward a fence from a point 20 m away, as shown below. The velocity of the ball as it leaves the kicker's foot is 17 m/s at angle of 35 degree above the horizontal. The top of the fence is 3 m
A ball is thrown upwards with an initial velocity of 16 m/s. What is the velocity of the ball 1.5 s later? After the ball leaves the hand of the thrower, what is the value of acceleration acting on the ball as it is rising upwards? 9.8x1.5 = 14.7.
Two students are on a balcony a distance h above the S street. One student throws a ball vertically downward at a speed vi ; at the same time, the other student throws a ball vertically upward at the same speed. Answer the following symbolically in terms
You toss a tennis ball straight upward. At the moment it leaves your hand it is at a height of 1.5 m above the ground, and it is moving at a speed of 7.8 m/s. (a) How much time does it take for the tennis ball to reach its maximum height? (b) What is the
