Part A
A box of mass m = 6.0 kg (moving in the
positive x-direction) has a velocity of 2 m/s at
t = 0, and has a velocity of 4.0 m/s at time
t = 2.0 s. From t = 0 to t = 2.0 s, a force F
acts on the box in the direction of motion.
Find the work done by Fr.
Express your answer with the appropriate
units.
