A water-skier lets go of the tow rope upon leaving the end of a jump ramp at a speed of v1 = 14.7 m/s. the skier has a speed of v2 = 12.7 m/s at the highest point of the jump.
Ignoring air resistance, determine the skier's height H above the top of the ramp at the highest point.
the answer is 1.38m
