Aball is thrown with initial speed voup an inclined plane. the plane is inclined at an angle above the horizontal, and the ball's initial velocity is at an angle 0 above the plane. choose axes with x measured up the slope, y normal to the slope, and z across it. write down newton's second law using these axes and find the ball's position as a function of time. show that the ball lands a distance r = 2v 2sin 0 cos(0 0)1(g cost) from its launch point. show that for given v and 0, the maximum 0 possible range up the inclined plane is r. = vo /[g(1 + sin oa
