A motorcycle daredevil plans to ride up a 2.1 m high 23.5 degree ramp, sail across a 8 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 12 m/s at that instant, and the rolling friction of his rubber tires (coefficient 0.02) is not negligible. Does...

speed, but this time she jumps at an angle 70 degrees at an angle
from the horizontal.

A skydiver jumps off of an airplane. The plane flies at an altitude of 4 km, and at a speed of 100 km/hr. The skydiver "jumps" by simply letting go of the plane and falling out. Gravity is the only thing affecting their motion until they open their parachute at a height of 2.5 km. After opening their parachute, they experience constant acceleration until they land perfectly, with...
