A stationary ball with a mass of 1.6kg, is struck by an identical ball moving with a velocity of 3m/sec.
After the collision the two balls stick together and contiue moving in a straight line, what is the final velocity?
Momentum before collision denote as p1
p1 = m*v1
where m = 1.6 kg, v1 = 3 m/s
p1 = 1.6 x 3 = 4.8 ...
The linear momentum physics of wo balls colliding and sticking together is examined and the final veloicty of the combined combination is determined
