ㄐ-X. 19X A tennis ball with mass 0.06 kg moves toward a wall with a velocity of 20 m/s. The tennis ball bounces off a wall and then has a velocity of -20 m/s. If a force of 10 N is applied to the ball from the wall to change the balls direction, how long was the ball in contact with the wall?

You dropped a 56 g tennis ball from a height of 12 m. A) What is the force of gravity acting on the ball? Air resistance on the ball during the fall is a constant upward force of 0.10 N. B) What is the net force acting on the ball? C) What is the net work done on the ball? Ignore negative signs in final answers (pick downwards as the positive direction) round all answers to 3 sig figs

A small, spring-loaded cannon launches a tennis ball from level ground with an initial speed vi at an angle θi with the horizontal. The tennis ball lands a horizontal distance R from its launch point. The highest point the tennis ball reaches during its flight is a distance R/12 above the ground. In terms of R and g, find the following. (You may ignore air resistance.) (a) the time interval during which the tennis ball is in motion (b)the tennis...

A ball is tossed straight upwards with an initial velocity of .30.00 metres per second from a height of 20,000 meters. Assume that the only force acting on the object is acceleration due to Earth's gravity. Write out the position and velocity functions. With what velocity does the object hit the ground? When the object hits the ground, it bounces back up with one-fourth the speed that it had when it hit the ground. Determine the height of the ball...

A 15 meter long, vertical cannon is used to accelerate a 1.5 kg ball straight up into the air. A constant force of 18.5 N is used to accelerate the ball up the length of the cannon. a. What is the ball's velocity as it leaves the cannon? (assume no energy loss to 9. friction) What would the ball's velocity be as it leaves the cannon if there was a 10% energy loss due to friction while the ball was...

Explore A baseball is thrown from the top of a tall building with an initial velocity of 10 m/s from a height of h= 11.5 m above the ground. Find its speed when it reaches the ground (a) if its launch angle is 37°, and (b) if it is launched horizontally. Conceptualize As the baseball moves upward and to the right, the force of gravity accelerates it downward. The vertical component of its velocity decreases in magnitude until the baseball...
