m1= 6kg

u1= 10m/s

m2= 2kg

u2= -5m/s.

Before collision,

Momentum= m1u1 - m1u1

= (6)(10) - (2)(5)

= 60 - 10= 50kgm/s

After collision,

Momentum= (m1 + m2)V

= (6 + 2)V

= 8V

From the law of conservation of linear momemtum, the momentum before collision is equal to the momentum after collision.

50= 8V

V= 50/8= 6.25m/s.

Answer:m1= 6kg

u1= 10m/s

m2= 2kg

u2= -5m/s.

Before collision,

Momentum= m1u1 - m1u1

= (6)(10) - (2)(5)

= 60 - 10= 50kgm/s

After collision,

Momentum= (m1 + m2)xV

= (6 + 2)xV

= 8V

The momentum before collision is equal to the momentum after collision.

50= 8V

V= 50/8= 6.25m/s.
