Ocont
• Mamcatum before cellision =0.3 Kg m/s
mamentum afler collisien = (0.075 kg)
9l Given :
• mass of first ball, m.=25 g
• Initial velocity of ficst baii, U: 12 m/S
•Mass of secend ball, m2 = Sog
Inito vebcity of secondball, Uz=0
lwe know thit collision iseither Ciasdic or inelast ic, the mementum
is amays censerved. Camservatien of memenkm- mamentum before Collision
is equai te the momentum after the Collision.
• Imomentum befere collis ion = m, y tmz U -0
lwhere, m. mass of first bailL, M, =25g= 0.02S kg
0:3kgm/s=(0.0Zs Ka).
v=4 ms
The velacity of each ball after the Collisianis 4 mis
momentum ofter Collisien=
Lutting V=4 mis
mementum AFer collision = (o.075 ka)4 mıs)
mamentum afier Cellision = 0,3 Ka m/s
• U, - Initiai velacity of first ball, U = 12 m/s
• m2 = mass of second ball, Ma = Soa=0.050 kg
•U2 = laitial veiasity df seund buil Uz =0
Put all these into eauasion D
•momentum before Collis ian = (o.025 kg) (12 mis)+ (0.050 kg) (0)
- momentum before the Collision = 0.3 kg m/s
Because the Cellision between the first and sesund ball is
inelostic, the twe mass behaves as u Single mass.
Momentum after Collision = (m,+m;)v
lWhere v is velocity afer collision
Putting mi=0.025 Kg and mz =0.050 ky
momentum ofer Coliston = (0.025 kg + 0.050 Kg) V
Momentum OFAer collision= (0.075 ky)v
Applying Conservition of mumentum-
momentum before Collisien= momentum aAer colision
