Question

A string pulls horizontally on a cart so that it moves at increasing speed in positive x x -direction along a smooth, frictionless, horizontal surface. At moment of time t1 t 1 , when the cart is moving medium-fast, the pulling is stopped abruptly. Use a vertical y y -axis with the positive direction pointing up. Choose the correct description of what happens to the cart’s motion when the pulling stops.

Answer 1

When the pulling on the cart is abruptly stopped at moment t1, the motion of the cart along the smooth, frictionless, horizontal surface will continue in the positive x-direction with a constant velocity. The cart will not experience any change in its speed or direction immediately after the pulling is stopped.
