Darius the dare devil plans to launch his rocket car at the top a ramp inclined at 20.0 degrees to the horizontal over a pit of fire 20 m in diameter, unfortunately the rocket motor fails at the foot of the ramp, when his speed is 19.3 m/s. The rolling friction of the car is 0.020. The height of the ramp is 1.70 m. Where will he land? (Will he burn?)
