Multiple Choice
A particle that is subjected to a variable force travels a distance of 20 m in a straight line in the same direction as the force. The force varies as follows:
First, 5.0 m and F = 0
Next, 5.0 m and F = 3.0 N
Next, 5.0 m and F = 6.0
Last, 5.0 m and F decreases uniformly from 6.0 N to zero
