2D Impulse
a) A particle of mass 0.25 kg is moving with speed 3
when it receives an impulse of 5 Ns in the direction of motion.
Find the new speed of the particle.
b) A particle of mass 0.25 kg is moving with speed 7 when it receives an impulse of 3 Ns in the opposite direction to the motion.
Find the new speed of the particle.
c) A particle of mass 0.25 kg is moving with velocity (3i + 7j) when it receives the impulse (5i – 3j) N s.
Find the speed of the particle immediately after the impulse.
