A skateboard weighing 46 N represented by force G lies on a

A skateboard weighing 46 N, represented by force G, lies on a hill that is inclined 38 degree to the horizontal, as shown. The figure is not drawn to scale. Complete the following. Do not round any intermediate computations, and round your answers to the nearest hundred Find the magnitude of the force Q required to prevent the skateboard from rolling down the hill. On Find the magnitude of the force C of the skateboard against the hill.

Solution

solution-

dividing G into the components along the plane and perpendicular to the plane

P=46sin38^o

to avoid rolling then P=Q

so,

Q=46sin38^o

Q=28.32N

b)

C=46cos38^o

C=36.24N
