A cart with frictionless wheels  is initially moving at a constant velocity on a horizontal surface. Suddenly, rain starts falling vertically down into the cart. The rain drops come to a stop with respect to the cart after hitting it, and water begins accumulating in the cart. Consider the following statements: The cart will keep moving at constant velocity because the rain falls vertically, so that it can’t change the horizontal component of momentum. The cart will keep moving at constant velocity because the total mechanical energy of the cart-water system is conserved. The cart will slow down because the horizontal component of the momentum of the cart-water system is conserved. Which of the above statements must be true about this situation?

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

The carpal tunnel contains the _________ which results in _________ in carpal tunnel syndrome

A spaceship drifts sideways in outer space from point P to point Q as shown in the figure. The spaceship is subject to no outside forces. Starting at position Q, the spaceship’s engine is turned on and produces a constant thrust (force on the spaceship) at right angles to the line PQ. The constant thrust is maintained until the spaceship reaches another point R in space. As the spaceship moves from Q to R, its speed is

An empty office chair is at rest on a floor. What force(s) is (are) acting on the chair?
