Homework Statement
An olympic athlete with [itex]~30[/itex] kg mass is participating in pole vaulting. The athlete runs and, at the moment of the jump, he has a velocity of [itex]~10[/itex] m/s. Calculate the maximum height he can reach.
To solve these kinds of problems, we can just convert all the kinetic energy the athlete develops during the motion to gravitational potential energy, and find the point which it has zero kinetic energy. But what I'm having trouble with is to calculate the mass of the athlete given initial velocity and the maximum height.
2. Homework Equations
The Attempt at a Solution
Evidently, If I try to use the conservation of energy formula for the athlete [tex]\frac{1}{2}mV_0^2 = mgh[/tex]then the masses will just cancel each other and I won't go anywhere. Thanks for the help.
