. Emily pushes a 38.8 kg grocery cart of groceries by exerting a 76.0 N force on the handle inclined at 40.0 degrees below the horizontal. What are: a. The horizontal and vertical components of Emily’s force

b. The acceleration of the cart?

a)

b) a = 1.5 m/s²

Explanation:

a) The horizontal and vertical components of Emily's force can be found knowing the angle and the exerted force.

Since the handle is inclined at 40.0° below the horizontal we have:

b) The acceleration of the car can be calculated as follows:

We used the horizontal component of the force because the cart is moving in that direction.

Hence, the acceleration of the car is 1.5 m/s².    

I hope it helps you!
