Answer: p = 80 kg.m/s

Explanation: Momentum is expressed as the product of mass and velocity.

p= mv

= 40 kg ( 2 m/s)

= 80 kg.m/s

Answer:

The boy's momentum = 80kgm/s

Explanation:

Momentum (P) =mass x velocity

Where, velocity(speed) =2m/s

Mass of the boy=40Kg

Momentum (P)=(40kg) x (2m/s) = 80kgm/s.
