A block of mass m = 5.3 kg is pulled up a 0 21° incline as in the figure below with a force of magnitude F = 36 N.
(a) Find the acceleration of the block if the incline is frictionless. (Give the magnitude of the acceleration.)
3.28
m/s²
(b) Find the acceleration of the block if the coefficient of kinetic friction between the block and incline is 0.11. (Give the magnitude of the acceleration.)
