A daredevil on a motorcycle leaves the end of a ramp with a speed of 29.5 m/s as in the figure below. If his speed is 27.1 m/s when he reaches the peak of the path, what is the maximum height that he reaches? Ignore friction and air resistance.

    Well I do not see your picture but if energy is conserved

    m g (increase in height) = (m/2)(29.5^2-27.1^2)
    mass cancels
    increase in height =(29.5^2-27.1^2)/(2g)
