Question

A body of mass 2kg moves with an acceleration 3m/s2 . The change in momentum in one second is

Answer 1

Answer:

6kgms⁻¹

Explanation:

mass, m = 2 kg

acceleration, a = 3 m/s²

time, t = 1 s

We know that,

v = u + at

v − u = at

v − u = 3 × 1

v − u = 3 m/s

change in momentum, Δ p = m ( v − u )

⇒ Δ p = 2 × 3 = 6 kgms⁻¹
