Question

In 1993, Cuban athlete Javier Sotomayor set the world record for the high
jump. The gravitational potential energy associated with Sotomayor’s jump
was 1,970 J. Sotomayor’s mass was 82.0 kg. How high did Sotomayor jump

Answer 1

Explanation:

We use the formula

PE = mgh

where

PE = potential energy (J)

m = mass (kg)

g = acceleration due to gravity = 9.8 m/s^2

h = height (m)

Substituting,

1970 = 82(9.8)(h)

h = 2.45 m
