A ball of mass 1.5 kg is thrown upward. It leaves the thrower's hand with a velocity of 10 m/s. What is the average force exerted by the hand on the ball during the 0.25 s that the ball is being stopped?

A baseball catcher moves his glove away from a 39.0 m/s fastball as he catches it. If the average force he exerts on the ball is 1.22  103 N, how far does the glove move? Assume constant deceleration of the ball, which has a mass of 0.149 kg.

A soccer goalkeeper accelerates a ball from rest at a speed of 15 m / s for the time that his foot is in contact with the ball (approximately 0.19 s). If the ball has a mass of 0.44 kg, what average force does the goalkeeper exert on the ball?

A baseball (m= 150 g) approaches a bat horizontally at a speed of 43.9 m/s (98.2 mi/h) and is hit straight back at a speed of 52.6 m/s (118 mi/h). If the ball is in contact with the bat for a time of 1.27 ms, what is the average force exerted on the ball by the bat? Neglect the weight of the bat, since it is so much less than the force of the bat. Choose the direction of the incoming ball as the positive direction. Number i Units VO Vf

A baseball with a mass of 148 g is thrown horizontally with a speed of 39.1 m/s (87 mi/h) at a bat. The ball is in contact with the bat for 1.00 ms and then travels straight back at a speed of 45.3 m/s (101 mi/h). Determine the average force exerted on the ball by the bat. Neglect the weight of the ball (it is much smaller than the force of the bat) and choose the direction of the incoming ball to be positive. (Indicate the direction with the sign of your answer.)

A 0.6 Kg football is thrown with a velocity of 22 m/s to left. A stationary receiver catches the ball and brings it to rest in 0.03 s. What is the force exerted on the ball by the receiver? Show the procedure, result with units and direction

After falling from rest from a height of 31 m, a 0.60-kg ball rebounds upward, reaching a height of 21 m. If the contact between ball and ground lasted 2.5 ms, what average force was exerted on the ball?

Jason takes off from rest across level water on his jet-powered skis. The combined mass of Jason and his skis is 75 kg (the mass of the fuel is negligible). The skis have a thrust of 200 N and a coefficient of kinetic friction on water of 0.10. Unfortunately, the skis run out of fuel after only 27 s. How far has Jason traveled when he finally coasts to a stop?

A hockey player slaps a puck into a cushion, which brings the puck to rest.  If the puck's initial velocity was +40 m/s and it has a mass of 170 g, what force does the cushion apply to the puck?  Assume the cushion acts on the puck for 0.03 s and the surface that the puck slides on is frictionless.

A Maxim machine gun fires 431 bullets per minute. Each bullet has a mass of 12g and a velocity of 686m/s.What is the average force that the impact of these bullets exerts on a target? Assume the bullets penetrate the target and remain embedded in it. Calculate answer to one decimal.
