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...

Topic: COLLISIONS. Impulsive Forces Show complete solutions and drawing or diagram. 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 d.) The "land divers" of Pentecost Island (Vanuatu) jump from platforms 21 m high. Long liana vines tied to their ankles jerk them to a halt just short of the ground. If the pull of the liana takes 0.020 s to halt the diver, what is the average acceleration of the diver during this time interval? If the mass of the diver is 64 kg, what is the corresponding average force on his ankles?
