what will be the kinetic energy of a 100 gram ball if we apply 1 newton force on it
I forgot to answer this question.
Applying 1N to a 100g mass will provide an acceleration of exactly 10m/s^2. The kinetic energy will increase with time as the mass increase in velocity.
After 1 second the velocity is 10m/s, so Ke is therfor 1/2 * 0.1(10*10)= 5 Joule.
After 2 seconds, Ke is 20 Joule because velocity is 20m/s
After 3 seconds, Ke is 45 Joule because velocity is 30m/s
4 seconds, 80 Joule because velocity is 40m/s.
