Question

The shopper pays for his groceries and pushes the shopping cart out of the store, where he encounters a ramp that helps him move the cart from the sidewalk down to the parking lot. What force accelerates the cart down the ramp?

Answer 1

Gravity accelerates the cart down the ramp

Answer 2

Gravitational force will accelerate the cart.

Step-by-step explanation:

In the given case the cart is on a ramp in this situation the gravitational force is applied normally on the cart and its horizontal component which is
`mgcos\theta` and its vertical component which is
`mgsin\theta` acting along the ramp.

In this situation as we the acceleration is increased by a factor
`gsin\theta` which helps in increasing its acceleration.

Therefore acceleration due to gravity will accelerate the cart.
