What is the kinetic energy of a 150 kg object moving at a velocity of 15 m/s?
25312.5 j
16875 j
50625 j
33750 j

16875joules

Explanation:

Mass=m=150kg velocity=v=15m/s

kinetic energy =(m x v^2)/2

Kinetic energy =(150x15^2)/2

Kinetic energy =(150x225)/2

kinetic energy =33750/2

Kinetic energy =16875joules

because if the tool that you are using is not balanced it there would be false mass.

find the surface area of the sphere to the nearest square unit. use a calculator.
