1. If a 100 kg running back runs at 9 m/s, what is the running back's kinetic energy?
O 4050 J
O 450 J
O 11.11 J

For this case we have that by definition, the kinetic energy is given by the following formula:

Where:

m: It is the mass

v: It is the velocity

According to the data we have to:

Substituting the values we have:

finally, the kinetic energy is

Option A

it becomes positively charged by charging it

causes

fossil fuels burn

cities become more industrialized

human population grows worldwide
