A tennis ball may leave a top player's racket on the serve with a speed of 65.0m/s If m Ap the ball's mass is 0.0600 kg, what is the change of momentum of the ball if it started from rest? How much force is required to stop a 60 kg person traveling at 30m/s during a time of: a. 5.0 seconds __ b. 0.50 seconds __ c. 0.05 seconds __ 4. A 1200-kg car is brought from 25m/s to 10m/s over a ti time period with a force c of -600N Determine the time it took for this change in momentum. A 0.10-kg hockey puck decreases its speed from 40m/s to 0m/s in 0.025 seconds. Determine the force that it experiences. A force of 6.0 N acts on a 4.0 kg object for 10.0s. What is the object's change in momentum?

1. The change in momentum of a 1000 kg car moving from 1 m/s to 8 m/s is calculated as follows: 2. The change in momentum of the tennis ball is calculated as follows: 3. The force required to stop a 60 kg person traveling at 30 m/s during a time of:a. 5.0 seconds: b. 0.50 seconds: c. 0.05 seconds: 4. The time it took for the 1200-kg car to change its momentum from 25 m/s to 10 m/s with a force of -600 N is calculated as follows: 5. The force experienced by the 0.10-kg hockey puck as it decreases its speed from 40 m/s to 0 m/s in 0.025 seconds is calculated as follows: 6. The object's change in momentum when a force of 6.0 N acts on a 4.0 kg object for 10.0 s is calculated as follows:
