Answer :
kinetic energy of a 3 kg is 6 joules.
It is given that,
Mass of the ball, m = 3 kg
Speed of the ball, v = 2 m/s
The energy that is possessed due to the motion of an object is called the kinetic energy of the ball. Its formula is given by :
KE=mv²(½)
=(3kg)(2m/s)²(½)
=3(4)(½)J
=6 J
E = 6 joules
So, the kinetic energy of the ball is 6 joules. Hence, this is the required solution.
