mU1 + mU2 = mV1 + mV2
(5 × 6) + (3 × 4) = 5V + 3V
30 + 12 = 8V
42 = 8V
V = 5.25m/s
The velocity of the ball after the collision is 5.25m/s.
Speed is the rate at which an object travels along a path over time, whereas velocity is the speed and direction of an item's motion.
Velocity can be defined as the rate at which something moves in a specific direction. as the speed of a car driving north on a highway or the pace at which a rocket takes off. Because the velocity vector is scalar, its absolute value magnitude will always equal the motion's speed.
