A motor stunt driver tries to pull off an exhibition by taking off an inclined ramp 53o above the horizontal across to the other side of the river 40 m away. The landing deck is 15 m lower than the point where the driver last took off. The height from the water level to the take-off point is 100 m. Ignoring the air resistance, determine: a) What should be the speed (m/s) of the motor in order for him to land just at the edge of the deck? b) If the motor had just half of the velocity in part (a), how far (m) is the driver from the bottom of the river?
