Question

A motorcycle daredevil plans to ride up a 2.0-m-high, 20∘ ramp, sail across a 10-m-wide pool filled with hungry

crocodiles, and land at ground level on the other side. He has done this stunt many times and approaches it with confidence. Unfortunately, the motorcycle engine dies just as he starts up the ramp. He is going 10.6 m/s at that instant, and the rolling friction of his rubber tires (coefficient 0.02) is not negligible. Justify your answer by calculating the distance he travels through the air after leaving the end of the ramp.

Express your answer with the appropriate units.
