Answer:
<u><em>20 m/s.</em></u>
Explanation:
Mass of body m: 10kg
The kinetic energy of the body is given as;
Value of Kinetic energy K.E = 2000 Joules
V is the body's velocity, and M is the body's mass.
Calculating the value of velocity;
=
Velocity maintained by the body having a kinetic energy of 2000J is
20 m/s.
