(a) Salim who participates in motor race, leaves the end of a ramp with a speed of 90km/hr as in Figure. If his speed is 85.0 km/r when he reaches the peak of the path, 85 km/h what is the maximum height that he reaches? Ignore friction and air resistance. 90 km/h (b) A body of mass 6 kg is acted upon by a force of 5N is moving along a rough floor at a constant speed of 3.5 m/s. Calculate the power consumed in 15 s, and the force of friction acting on the object.
