Question

What is the kinetic energy of a 50-kg child running to catch the school bus at 2 m/s

Answer 1

Answer:

100 J

Step-by-step explanation:

The formula for kinetic energy is as follows:

$\boxed{KE= \frac{1}{2} mv²}$

where

KE= kinetic energy (J)

m= mass (kg)

v= velocity (m/s)

Given: m= 50 kg, v= 2 m/s

Substituting the given information into the formula:

KE

= ½(50)(2²)

= ½(50)(4)

= 100 J
