A bowling ball accidentally falls out of the cargo bay of an airliner as it flies along in a horizontal direction. As observed by a person standing on the ground and viewing the plane as in the figure at right, which path would the bowling ball most closely follow after leaving the airplane? Fig14.jpg

The figure depicts a hockey puck sliding with constant speed vo in a straight line from point “a” to point “b” on a frictionless horizontal surface. Forces exerted by the air are negligible. You are looking down on the puck. When the puck reaches point “b,” it receives a swift horizontal kick in the direction of the heavy print arrow. Had the puck been at rest at point “b,” then the kick would have set the puck in horizontal motion with a speed vk in the direction of the kick. Fig8(1).jpg Along the frictionless path that this puck travels in after the kick, the main force(s) acting on the puck after receiving the kick is (are):

In the figure below, student “a” has a mass of 95 kg and student “b” has a mass of 77 kg. They sit in identical office chairs facing each other. Student “a” places his bare feet on the knees of student “b”, as shown. Student “a” then suddenly pushes outward with his feet, causing both chairs to move. Fig28.jpg During the push and while the students are still touching one another:

The two metal balls of the previous problem roll off a horizontal table with the same speed. In this situation:

The position of two blocks at successive 0.20-second time intervals are represented by the numbered squares in the figure below. The blocks are moving toward the right. Fig20.jpg The accelerations of the blocks are related as follows:

A large truck breaks down out on the road and receives a push back into town by a small compact car as shown in the figure below. Fig15.jpg After the car reaches the constant cruising speed at which its driver wishes to push the truck:
