- A daredevil on a motorcycle leaves the end of a ramp with a speed of 34.6 m/s as in the figure below. If his speed is 33.0 m/s when he reaches the peak of the path, what is the maximum height that he reaches? Ignore friction and air resistance.=mWhich of the following statements are true? Select all correct. Question 3 options: Energy has units of Joules, which can be written as kg m/s2. Potential energy can be positive, zero, or negative. The kinetic energy of an object depends on both its speed and direction. Kinetic energy can be positive or zero, but never negative. Energy is a vector. Conservation of energy states that the kinetic energy is constant.In the figure, a 3.7 kg block slides along a track from one level to a higher level after passing through an intermediate valley. The track is frictionless until the block reaches the higher level. There a frictional force stops the block in a distance d.
