- A baseball of mass m = 0.34 kg is dropped from a height h1 = 2.4 m. It bounces from the concrete below and returns to a final height of h2 = 1.85 m. Neglect air resistance. Select an expression for the impulse I that the baseball experiences when it bounces off the concrete. What is this impulse, in kilogram meters per second? If the baseball was in contact with the concrete for t = 0.01 s, what average force Fave did the concrete exert on the baseball, in newtons?Consider an automobile accident in which a 1000 kg car strikes a tree in an inelastic collision. The speed of the car just before the collision was 72 km/hr. The duration of the impulse is 0.01s. What force does the passenger experience? In the same automobile, a passenger of mass 50 kg is sitting, unrestrained, in the front seat. The speed of the passenger was 72 km/hr before the collision and zero afterewards. The duration of the impulse that changes is or her momentum is again 0.01 s. What force does the passenger experience? Same automobile accident, except that the passenger is restrained by a seat belt and an air bag explodes at the moment of impact. The passenger's speed still changes from 72 km/hr to zero, but the air bag slows the time during which this change occurs to 0.01 s. What force does the passenger experience?An impulse of 10 Ns is applied to an object. If you know the force acting on the object was 20 N, what was the time interval the force occurred?
