A body of mass 2kg is placed on a rough inclined plane ,whose angle of inclination is 30°.

Find the force acting down the slope and the acceleration if a frictional force of 5N acts between the body and the surface?

1 answer

down the slope due to gravity=mg*sinTheta
up the slope due to friction: 5N
net force down slope= forceduegravity-friction=ma
a= g*sinTheta-5/m
