Question

fastest humans can reach speeds of about 11 m/s. part a 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? express your answer to two significant figures and include the appropriate units.

Answer 1

6.17 m

Step-by-step explanation:

speed, v = 11 m/s

Let the mas is m.

As according to the question

Potential energy = kinetic energy

m x g x h = 0.5 m v²

where, h is the height raised.

9.8 x h = 0.5 x 11 x 11

h = 6.17 m

Thus, the height raised is 6.17 m .
