A 2.0 kg block is pulled up a rough inclined plane that makes an angle of \(30^{\circ}\) with the horizontal by a constant horizontal force of \(15\) N. The coefficient of kinetic friction between the block and the plane is \(0.20\). The block starts from rest at the bottom and moves \(5.0\) m along the plane.\n(a) Find the speed of the block when it reaches the top of the incline.\n(b) Find the average power delivered by the horizontal force during the motion.
