Question

A car with kinetic energy 100 joule is moving on a horizontal Road now 200 joule work is done on the car. What is the
the change in kinetic energy is

Answer 1

Hi friend,

Initial kinetic energy= 100 J

Final kinetic energy= 200 J

(Note:- work done= kinetic energy).

Change in kinetic energy= Final kinetic energy- initial kinetic energy

Change in k.e= 200-100

Change in k.e = 100J. Kinetic energy = 100+ 100 Kinetic energy= 200J.

Hope this helped you a little!!!!

Answer 2

Now
Kinetic energy 2- kinetic energy 2 = work done
K1 is 100
So
K2-100=200
K2=300
So Change in kinetic is 300 joule
