Question

The kinetic energy of a moving body varies directly
with its mass when its velocity is constant and with
the square of its velocity when its mass is constant.
A body has a mass of 7.2 kg and a velocity of
0.2 m/sec and a kinetic energy of 0.144 joules. Find
the kinetic energy of a body having a mass of 3.6 kg
and a velocity of 0.8 m/sec (in joules).​

Answer 1

Answer:

Velocity will complete

Answer 2

Answer:

Step-by-step explanation:

K.E= 1/2*m*v².

For 3.6KG mass and 0.8m/sec velocity

K.E=1/2*3.6*(0.8)²=1.152joules.
