Answer:
Given A 1kg block at origin has an initial velocity 2 m/s a force as shown in the f-x graph starts to act on it
No other forces are acting on it. So we need to find the change in kinetic energy
We know that area under F – X curve will be
= 3 x 1 + 1/2 x 1 x 3 – 1/2 x 2 x 3 + 1/2 x 1 x 3 + 3 x 1
= 6 J
So ω = Δ k
Δ k =6
