The world's fastest humans can reach speeds of about 11 m/s. In order to increase his gravitational potential energy by an amount equal to his kinetic energy at full speed, how high would such a sprinter need to climb?

How do you set this up?

• physics -

(1/2) m (121) = m (9.8) h

h = 121 /(9.8*2) = 6.17 meters

• Thank you! -

That really helped thank you very much
