Problem 2E

BIO How High Can We Jump?? The maximum height a typical human can jump from a crouched start is about 60 cm. By how much does the gravitational potential energy increase for a 72-kg person in such a jump? Where does this energy come from?

Step-by-Step Solution:
Step 1 of 3

Solution 2E The expression for gravitational potential energy is given by E = mgh, where m is the mass of the body, g is acceleration due to gravity and h is the height of the body from ground. Given that, h = 60 cm = 0.6 m m = 72 kg g = 9.80 m/s 2 Therefore, the increase in gravitational potential energy is 2 E = 72 kg × 9.80 m/s × 0.6 m...
