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

leva [86]

Answer:

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
