Question

A small cart is rolling freely on an inclined ramp with a constant acceleration of 0.50 m/s² in the x-direction. At time t=0, the cart has a velocity of 2.0m/s in the +x-direction. If the cart never leaves the ramp, describe the motion of the cart at time t>5s.

A) The cart continues to move with a constant acceleration of 0.50 m/s²in the +x-direction.

B) The cart comes to a stop and remains stationary.

C) The cart moves with a decreasing acceleration in the +x-direction.

D) The cart moves with an increasing acceleration in the -x-direction.

Answer 1

The cart continues to move with a constant acceleration of 0.50 m/s² in the +x-direction when t>5s.

Step-by-step explanation:

The cart continues to move with a constant acceleration of 0.50 m/s² in the +x-direction when t>5s. This means that the cart's velocity will continue to increase at a constant rate in the positive x-direction. The cart will not come to a stop or change direction, as there is no indication of a negative acceleration or any external forces acting on the cart.
