A block of mass \(800\ \text{kg}\) is pulled up a \(30^{\circ}\) incline by a constant horizontal force of magnitude \(8000\ \text{N}\). The coefficient of kinetic friction between the block and the plane is \(\mu_{k}=0.2\). The block starts from rest at the bottom and moves \(10\ \text{m}\) along the incline. (a) Calculate the work done by the horizontal force. (b) Determine the increase in kinetic energy of the block. (c) Find the speed of the block after moving the \(10\ \text{m}\). (Take \(g=9.8\ \text{m s}^{-2}\).)
