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.
The solution is comprised of several physics problems related to momentum and impulse. By conservation of momentum and impulse- momentum theorem, the detailed solution are provided.
