Question

A person is riding their bicycle along a straight

road at a speed of 7.9 m/s. In total, they have a
mass of 88 kilograms. What is the kinetic energy,
in joules, of the person with their bicycle?

Answer 1

Answer: 2746.04 joules

Step-by-step explanation:

The equation K=(1/2)(m)(v)^2 will provide the answer.

K stands for Kinetic Energy

m stands for mass (88 Kg)

v stands for velocity (7.9 m/s)

When you sub in these variables you get:

K=(1/2)(88 Kg)(7.9 m/s)^2

K=2746.04 joules
