Block M = 7.50 kg is initially moving up the incline and is increasing speed with
a = 3.82 m/s2 . The applied force F is horizontal. The coecients of friction
between the block and incline are s = 0.443 and k = 0.312. The angle of the incline is
25.0 degrees.
(a) What is the force F (N)?
(b) What is the normal force N (in N) between the
block and incline?
(c) What is the force of friction (N) on the block?
