Question

Chapter 6: Momentum and collision Q1- A body of mass lkg travelling with a speed 3m/s collides with a stationary body of mass 0.5kg, and they stick together. What speed do the two bodies have after the collision? Answer: 2 m/s Before collision VA After collisior VI Q2-Two particles, A and B, of masses ma m and me-2m collide head-on with speeds of vAi 2u and vB- -u. Find the speeds vAr and ver of both particles after the collision. Answer: VAr-2u and vBr u. Before collision After collision Q3- A body of mass lkg moving with a speed 3ms-1 collided inelastically with a stationary body of mass 2kg. After the collision, the body of mass lkg was stationary. How much energy was converted to sound and heat in this collision? Answer: 2.25 Before collision After collision m sont/heat Q4- A bicycle has a momentum of 24 kg.m/s. What momentum would the bicycle have if it had a. twice the mass and was moving at the same speed? Answer: 48 kg·m/s b.... one-half the mass and was moving with twice the speed? Answer:24 kg.m/s c. the same mass and was moving with one-half the speed? Answer:12 kg.m/s d.... three times the mass and was moving with one-half the speed? Answer:36 kg.m/s e.... three times the mass and was moving with twice the speed? Answer:144 kg.m/s Before collision After collision VA VBr A completely elostic colsion in 20 05- Think about this question:
