How fast is a 180 kg motorcycle traveling if it has 36000 J of kinetic energy?

how much kinetic energy does an 80 kg football player have if he is running at 3 m/s?

20 ms⁻¹

360 J

Explanation:

Kinetic energy is the energy possessed by a moving object solely due to its motion.

You can get the K. E. of an object using the equation,

K. E. = (1/2) mv² where all terms in usual meaning

So you get,

K. E. = 36000 = (1/2) * 180*v²

v = 20 ms⁻¹

Also,

K. E. = (1/2) * 80*3² = 360 J
