Please help me ill give brainliest if right

3000kg

Explanation:

Given parameters:

Speed = 20m/s

Kinetic energy  = 600000J

Unknown:

Mass  = ?

Solution:

Kinetic energy is the energy due to the motion of a body.

It is expressed as;

  K.E  = m v²  

m is the mass

v is the speed

  Now find m;

        600000 =    x m x 20²

        600000 = 200m

         m  = 3000kg
