Use the diagram below of a man skiing downhill to answer question #1.

A man is skiing downhill. As he skis, a strong wind begins to constantly blow towards him. The forces of the wind are greater than the force that is moving the man forward. What will happen to the speed of the man while the strong wind is blowing towards him?

• The man will continue to slow down the entire time he is moving until he stops.

• The man will move at a constant speed for a while, and then slow down until he stops.

• The man will move at a constant speed for the entire time until he stops.

• The man will slow down for a while and then move at a constant speed until he stops.

Use the diagram and data table to anwser question #7.

For an investigation, a student measures the speed of a cart as it rolls down a ramp at different locations. The student then records data in the table below. Which of the following 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.
