For an investigation, a student measures the speed of a cart as it rolls down a ramp. The student then records data in the table shown above. Which of these best explains the student’s data? A.
The speed of the cart decreases as the cart rolls down the ramp because of friction between the cart and the ramp.

B.
The speed of the cart increases as the cart rolls down the ramp because the force acting on the cart is greater than the force of gravity.

C.
The speed of the cart increases as the cart rolls down the ramp because the forces acting on the cart are unbalanced.

D.
The speed of the cart decreases as the cart rolls down the ramp because the forces acting on the cart are balanced.
