of 5 ms-1. If the velocity of the object is tripled,
the change in kinetic energy of the object is:​

Answer 1

Answer:

change. 8

%change 800

Thanks for Reading

Answer 2

Explanation:

present ke=1/2*10*25=125

velocity after tripled is 15m/s.

ke=1/2*10*225=1125

change in ke is 1000kgm^2/s^2

percentage is 800%
