If his speed is 31.0 m/s when he reaches the peak of the path, what is the maximum height that he reaches? Ignore friction and air resistance. m A daredevil on a motorcyle is at the end of a ramp that is sloped up to the right. An arrow parallel to the ramp's surface is above the daredevil. A dotted-line path traces the trajectory of the daredevil. The path extends up to the right, initially parallel to the surface of the ramp, and decreases in slope until it reaches a maximum, whereupon it extends down to the right with increasing slope magnitude. The vertical distance between the maximum and the highest point of the ramp is h. A horizontal arrow points to the right above the maximum.
