A 20kg truck is resting on a ramp inclined at an angle of 15 degrees. Calculate the components of the force of gravity on the truck that are parallel and perpendicular to the ramp.

OpenStudy (shamim):

weight of the truck is W=mg=20*9.8=196N

OpenStudy (shamim):

component along the ramp=\[196\sin15=127.46N\]

OpenStudy (shamim):

component perpendicular to the plane of ramp=\[196\cos15=148.9N\]
