Multiple Choice
Identify the choice that best completes the statement or answers the question.
 

 1. 

The coefficient of friction, mc001-1.jpgis a ratio that compares the friction acting on a dragged object to its weight, w. The relationships between the mass m and the acceleration a of an object that is being dragged across a flat surface, such as a table top, by a force F, is given by the equation mc001-2.jpg.

mc001-3.jpg

What formula can you use to find the coefficient of friction?
a.
mc001-4.jpg
c.
mc001-6.jpg
b.
mc001-5.jpg
d.
mc001-7.jpg
 

 2. 

When x pounds of force is applied to one end of a lever that is L feet long, the resulting force y on the other end is determined by the distance between the fulcrum (the lever's pivot) and the end of the lever on which the x pounds of force is exerted.
mc002-1.jpg

The formula relating the forces is mc002-2.jpgWhat formula can you use to find the length of the lever?
a.
mc002-3.jpg
c.
mc002-5.jpg
b.
mc002-4.jpg
d.
mc002-6.jpg
 

Short Answer
 

 1. 

The formula that relates the final speed of a car, sa001-1.jpgto its original speed, sa001-2.jpgis sa001-3.jpgwhere a is the car's acceleration and t is the time for which the acceleration acts. (The acceleration is the rate at which the car's speed is changing. If the car's speed is decreasing, a is negative and the car is said to be "decelerating.")
Rewrite the formula to find t. Show your steps.
