Question

A student s life was saved in an automobile accident because an airbag expanded i head. If the car had not been equipped with an airbag, the windshield would have motion of his head in a much shorter time. Compared to the windshield, the airbag. exerts a much smaller force causes a much smaller change in kinetic energy causes a much smaller change in momentum exerts a much smaller impulse does much more work Two bodies of unequal mass, placed at rest on a frictionless surface, are horizontal forces for equal times. Just after these forces are removed, the body will have: the smaller momentum the greater speed the greater acceleration the same momentum as the other body the greater momentum Blocks A and B are moving toward each other. A has a mass of 2.0 kg and a while B has a mass of 4.0 kg and a velocity of -25 m/s. They suffer a collision. The kinetic energy lost during the collision is: 5600 J 3750 J 1250 J 0 5000 J A 4-kg ball is dropped vertically from a height and it hits the floor with a ball rebounds vertically and reaches a height of 2 m above the floor. The on the ball during the contact with the floor is: 78 N.s 8 N.s 65 N.s 15 N.s 40 N.s
