What is the kinetic energy of a 1450 kg sports car traveling down the road with a speed of 30 m/s?

= 652500J

The easiest way to solve this problem is using the kinetic energy equation:

= mv²/2

A 1450kg sports car traveling down the road at a speed of 30m/s is kinectic energy will be:

= [(1450kg)(30m/s)²]/2 = 1305000kg-m²/s²/2

= 652500J

0.3x0.21x0.08kg=mass 1 sheet

mass 500 = 500xmass 1

volume pile = 0.3x0.2x0.048

density=mass/volume= 500xmass 1/0.3x0.2x0.048

it doesn't. it was imagined up in the middle ages.
