Question

A ball of mass 1kg moving with velocity 6m/s gets deflected by an angle of 60° without affecting the speed. Find the impulse imparted on the ball.​

Answer 1

Answer:

Explanation:

We know that Impulse = Force × time period.

But also,

Impulse= Change in momentum

Taking the momentum of the ball before collision as P1

P1= m ×v

P1= 0.1 kg × 10 m/s

P1= 1 kg×m/s

P2= Momentum of the ball after collision

P2= -(0.1×10) kg×m/s

P2= -1 kg×m/s

Impulse= Change in momentum= P1-P2

P1-P2= 1–(-1)= 2Ns

That is the answer.

Answer 2

Answer:

P1 - P2 = 2 = 2NS
