Answer 1

Basic formula required for the calculation :

Momentum(M) = Mass(m) × Velocity (v)

M¹ = mv

a.) When velocity is doubled :

Ans. M² = m×2×v

M² = 2(M¹)

Then, momentum is also doubled.

b.) When velocity is doubled and mass is halved :

Ans. M³ = ½×m×2×v

M³ = mv

M³ = M¹

Then, momentum remains same.

c.) When both velocity and mass is halved :

Ans. M⁴ = ½×m×½×v

M⁴ = ¼× mv

M⁴ = ¼(M¹)

Then, momentum becomes one - fourth.
