e.) A shotgun fires a slug of lead of mass 28 g with a muzzle velocity of 450 m/s. The slug acquires this velocity while it accelerates along the barrel of the shotgun, which is 70 cm long.
e1.) What is the impulse the shotgun gives the slug?
e2.) Estimate the average impulsive force; assume constant acceleration of the slug along the barrel.

Topic: COLLISIONS. Impulsive forces Show complete solution with diagram. b.) A large ship of 7.0 x 105 metric tons steaming at 20 km/h runs a ground on a reef, which brings it to a halt in 5.0 s. What is the impulse delivered to the ship? What is the average force on the ship? What is the average deceleration?
Topic: COLLISIONS. Impulsive forces Show complete solution with graph or drawing. a.) A stuntman of mass 77 kg belly-flops on a shallow pool of water from a height of 11 m. When he hits the pool, he comes to rest in about 0.050 s. What is the impulse that the water and the bottom of the pool deliver to his body during this time interval? What is the time-average force? b.) A large ship of 7.0 x 105 metric tons...

The women holds a 5.0 kg medicine ball. The women throws the ball to the man with a horizontal velocity of 2.5 m/s relative to the ice. What is her recoil velocity? What is the man's velocity after catching the ball? The man the throws the ball horizontally...
Topic: COLLISIONS. Inelastic Collisions in One Dimension Show complete solutions and diagram or drawing. 1.) A 25 kg boy on a 10 kg sled is coasting at 3.0 m/s on level ice toward his 30 kg sister. The girl jumps vertically and land on her brother's back. What is the final speed of the siblings and sled? Neglect friction. 2.) A 75 kg women and a 65 kg man face each other on a friction-less ice pond. The women holds...
