Question

A motor car with a mass of 1200kg moves from raced with uniform from acceleration and attend a maximum speed is 8m/s what is kinetic energy

Answer 1

Answer:

the answer is 38400 J .

pls thank  my answer and mark as brainliest.

Explanation:

m = 1200 kg

v = 8 m/s

kinetic energy = 1/2 * m * v^2

                         = 1/2 * 1200 * 8^2

                        = 1/2 * 1200 * 64

                         = 1/2 * 600 * 64

                         =  38400 J
