Question

what will be the kinetic enery of a body when its mass is made 4 times and the velocity is doubled​

Answer 1

Answer:

KE will be 16 times the original value

Explanation:

m = original mass

v = original velocity

Original KE = 1/2mv²

We are given:

new mass = 4m

new velocity = 2v

New KE = (1/2)*(new mass)*(new velocity)²

New KE = (1/2)*(4m)*(2v)²

             = (1/2)*4*m*4*v²

             = 4*4*(1/2)*m*v²

             = 16*Original KE

The new KE will be 16 times the original.
