If a sprinter
running at a speed of 10 meters per second couldconvert his/her
kinetic energy into upward motion, how high couldhe/she
jump?

The height jumped by the sprinter is 5.10 meters.

Explanation:

It is given that,

Speed of the sprinter, v = 10 m/s

We need to find the height jumped by the sprinter his or her kinetic energy gets converted into upward motion. It can be calculated using conservation of energy as :

g is the acceleration due to gravity

h = 5.10 meters

So, the height jumped by the sprinter is 5.10 meters. Hence, this is the required solution.
