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. Which of these best explains the student's data?

• the speed of the cart decreases as the cart rolls down the ramp because of friction between the cart and the ramp
• 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
• the speed of the cart increases as the cart rolls down the ramp because the forces acting on the cart are unbalanced
• the speed of the cart decreases as the cart rolls down the ramp because the forces acting on the cart are balanced

Two cars with different masses travel at the same speed down a hill toward a stop sign. What will happen when both cars apply brakes at the same time to stop?

• The car with the smaller mass will require less forces to stop than the car with the larger mass.
• The car with the larger mass will amintain its velocity while traveling down the hill.
• The car with the smaller mass will take longer to stop than the car with the larger mass.
• The car with the larger mass will have less inertia than the car with the smaller mass.
