Two objects each of mass 1.5 Kg are moving in the same straight line b...
Mass ofone of the objects,m1= 1.5 kg
Mass of the other object,m2= 1.5 kg
Velocity ofm1before collision,v1= 2.5 m/s
Velocity ofm2, moving in opposite direction before collision,v2= 2.5' m/s
(Negative sign arises because massm2is moving in an opposite direction)
After collision, the two objects stick together.
Total mass of the combined object =m1+m2
Velocity of the combined object =v
According to the law of conservation of momentum:
Total momentum before collision = Total momentum after collision
m1v1+m2v1= (m1+m2)v
1.5(2.5) + 1.5 (2.5') = (1.5 + 1.5)v
3.75' + 3.75 = 3v
v= 0
Hence, the velocity of the combined object after collision is 0 m/s.
