Question

A block of mass m = 5.4 kg is pulled up a = 23 incline as in the figure with a force of magnitude F = 35 N. Find the acceleration of the block if the incline is frictionless.

Answer 1

force down the plane due to weight= mg*cosTheta

net force= 35-mg*cosTheta=ma

solve for acceleration a.

Answer 2

thanks, this really helped.. but i had to use sin instead of cos
