1.	Two spherical balls of masses 2kg and 4kg move along the same line with velocities 1.5m/s and 2 m/s. They collide and after collision the second ball moves with a velocity 1.5 the m/s. Find the velocity of the first ball.
Answer» Heya mate...... It is given that m1= 2kg. m2= 3kg (masses of the bodies) U1=6m/s and u2=4m/s (where u1 and u2 are INITIAL velocities of the bodies) v1=? v2=3m/s (where v1 and v2 are final velocities of the bodies) We KNOW that momentum before collision= Momentum after collision And momentum = MassVelocity Therefore, m1u1+m2u2=m1v1+m2v2 26+34=2v1+3*3 12+12=2v1+9 2v1=15 v1=15/2=7.5 HOPE IT HELPS ✌ ✌ ✌
