I want the solution by the details steps handwritten please

B4. A child in a sledge slides down a snow covered hill that is angled 45 below the horizontal. The coefficient of friction between the sledge and the snow is p, = l/. At time 2' = l}, the speed of the sledge is u. m/s. (a) What is the acceleration of the sledge parallel to the hill? (b) Derive an expression for the distance the sledge has travelled down the hill at time t > 0. (c) At time t = 0. the child throws a ball with initial Speed 11: relative to the sledge and at an angle .3 above the hill. What is the initial velocity of the ball relative to the hill? (d) Find the angle t3 that the child should throw the ball so that they can catch it further down the hill (you should assume that the ball is caught at the same height above the sledge as it is thrown)
