The diagram above illustrates a ball of mass m sliding down a plank inclined at an angle of 0 to the horizontal. The kinetic friction between the ball and the plank is F and the acceleration of free fall is g. The net force on the ball along the plank is?
The force causing the ball to roll down the inclined plane is greater than the one pulling it up, resolving the force in its component we have \(mgsin\theta\)
therefore the Net Force acting on the ball = \(mgsin\theta\) - F
