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.

|Fg| = 196N
|Fparallel| = 196cos75
|Fperpen| = 196cos15

Is this correct?

anonymous · Answer

yes ,thats right.

anonymous · Answer

the force perpendicular to gravity is also force of friction, correct?

anonymous · Answer

frictional force will act parallel to the ramp in the opposite direction of motion of the truck
