Q1. A daredevil on the motorcycle leaves the end of a ramp with a speed of 36.0 m/s. If his speed is 34.20 m/s while he reaches the peak of the path, what is the maximum height that he reaches? Ignore friction and air resistance. In meters

Q2. A sled slides along a horizontal surface on that the coefficient of kinetic friction is 0.15. Its velocity at point A is 8.0 ;{rm m}/{rm s} and at point B is 5.0;{rm m}/{rm s} . Use the impulse-momentum theorem to find how long the sled takes to travel from A to B.
