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

wire in brush may conduct electricity from cell to drill and vice versa electrc shock possible

overcharge is the right answer system
