Mass of a body is increased by 16 times. What should be done to the velocity to maintain the same KE?
Velocity should be increased by 4 times
Velocity should be increased by 16 times
Velocity should be reduced to 1/4th the original value
Velocity should be reduced to 1/16th the original value
Velocity should be increased by 8 times
Mass of a body is increased by 49 times. What should be done to the velocity to maintain the same KE.
For the same kinetic energy of a body, what should be the change in its velocity if its mass is increased to four times its original value?
