Question

calculate the kinetic energy of a car of mass 625 kg moving with a velocity 12 meters /second
​

Answer 1

Answer:

ke = 1/2mv^2

=1/2 x 625 x 144

= 625 X 72

=45000 J

Answer 2

Answer:

We know kinetic Energy is

$0.5mv ^{2} \\ 0.5 \times 625 \times 12 \times 12 \\ = 45000joule$

M =625Kg

V=12m/s
