A block is moving with a velocity of 4.2 ft/s when a time-dependent force F is applied in the same direction as the motion of the block (see figure below).
F
Additional information you will need:
Weight of the block = 10 lb
Coefficient of friction: μ = 0.2
F(t) = 8t [F in lb, t in seconds]
a) Sketch the free body diagram (FBD) and the kinetic diagram (KD) for the block (10 points)
b) Find the velocity of the block when it has moved by 30 ft. (20 points)
