28-A 7.0 g bullet is fired into a 1.5 kg ballistic pendulum. The bullet emerges from the block with a speed of 200 m/s, and the block rises to a maximum height of 12 cm. Find the initial speed of the bullet?

18- A 730 N man stands in the middle of a frozen pond of radius 5.0 m. He is unable to get to the other side because of a lack of friction between his shoes and the ice. To overcome this difficulty, he throws his 1.2 kg physics textbook horizontally toward the north shore at a speed of 5.o m/s. How long does it take him to reach the south shore?

10-A 0.500kg football is thrown toward the East with a speed of 15 m/s .A stationary receiver catches the ball and brings it to rest at in 0.020 0 s. a) what is the impulse delivered to the ball as it's caught. b) what is the average force exerted on the receiver?

8- A 75.0 kg stuntman jumps from a balcony and falls 25.0 m before colliding with a pile of mattress. If the mattress are 1.0 s before it is brought, what is the average force exerted by the mattress on the stuntman?

17- A car of mass 1600 kg is travelling East at a speed of 25m/s along a horizontal roadway. When its brakes are applied, the car stops in 6.0 s. What is the average horizontal force exerted on the car while it is braking.
