A block of mass m = 5.4 kg is pulled up a θ = 24° incline as in the figure with a force of magnitude F = 35 N.
(a) Find the acceleration of the block if the incline is frictionless.
m/s2
(b) Find the acceleration of the block if the coefficient of kinetic friction between the block and incline is 0.11.

a) 35 - mgsin24 = ma
b) 35- mgsin24- Ff = ma
Fn = mgcos24
Ff = mu Fn
b) 35- mgsin24- Ff = ma
Fn = mgcos24
Ff = mu Fn
