Question

Calculate the force required to change the velocity of an object of mass 8 kg from 4 ms⁻¹ to 6 ms⁻¹ in 2 second.

Answer 1

Apply the formula f= ma

And has kinetic energy

Change

Use k.e.=½mv²

Answer 2

F = m*a here we see that F refers to force, m refers to mass and 'a' refers to acceleration.

Hence as you can see that mass plays a major role in determining inertia.

Hence in the given problem the coin with the highest mass is the five rupee coin.

Therefore it has the greatest inertia
