Question

The kinetic energy of an object of
mass, m moving with a velocity
of 5 m's is 25 J. What will be its
kinetic energy when its velocity
is doubled? What will be its
kinetic energy when its delocity
is increased three times?​

Answer 1

Answer:

mark me as brainliest

Explanation:

K.E=1/2mv^2

m is constant

K.E is directly proportional to v^2

So,when the velocity is doubled:

K.E=625J

TRIPLED:

K.E=2025J
