By using law of conservation of momentum equation
m1u1 = (m1 + m2)v
v = m1u1 / (m1 + m2)
= [(10 * 10^-3) * 100] / [ (10 * 10^-3) + 1]
= 0.99 m/s
The final velocity of system will be 0.99 m/s (≈ 1 m/s)
m1u1 = (m1 + m2)v
v = m1u1 / (m1 + m2)
= [(10 * 10^-3) * 100] / [ (10 * 10^-3) + 1]
= 0.99 m/s
The final velocity of system will be 0.99 m/s (≈ 1 m/s)
