Question

A skier approaches the base of an icy, frictionless hill with a speed of Vo. As the skier travels up the slope, the skier slows down. Find the HORIZONTAL and VERTICAL accelerations, NOT the acceleration of the slope. Use the x-y axes shown with horizontal rightward and vertical upward as positive. The initial velocity, Vo = 10.2 m/s The angle of the hill, b = 15° Cannot figure this thing out.I tried using -9.8Cos/Sin(15 but that was incorrect

Answer 1

In the horizontal direction , there is no force acting , hence

a_x = horizontal component = 0 m/s²

In the vertical direction , there is force of gravity acting in downward direction, hence

a_y = Vertical component = - 9.8 m/s²
