A bicycle initially moving with a velocity 8m/s accelerates for 6s at a rate of 4m/s^2 . What will be its final velocity
A ball of mass 4 kg moving with a velocity of 12 m/s impinges directly on another ball of mass 8 kg moving with velocity of 4 m/s in the same direction. Find their velocities after impact (if e = 0.5)
