Answer 1

Answer:

d)125kgm/s

Step by step explanation

Given: mass of the cannon 500 kg,

recoil speed 0.25 m/s

Momentum m × v

500 x 0.25 = 125 kg m/s.

Answer 2

Answer:

(d) 125 kgm/s

Explanation:

Momentum = mv, where m stands for mass, and v stands for velocity.

So,  Momentum = {500kg (mass)  x  0.25 (velocity)  }    kgm/s (unit)

                           = 125 kgm/s
