Answer:
1. 30 Kg.m/s
2. 20 m/s
Explanation:
1.
Momentum is given as the product of velocity and mass, expressed by the formula p=mv where p represnt momentum in kgm/s, m represent the mass of an object in Kg and v represent the velocity in m/s. Note that for momentum, direction is critical. For the given case, since mass is given as 5kg and velocity as 6 m/s then we directly substitute to obtain momentum as p=5*6=30 kg.m/s
2
We still use the formula of momentum as p=mv but making v the subject of the formula then [tex]v=\frac {p}{m}[/tex] and substituting p with 24000 kg.m/s while m with 1200 kg we obtain that [tex]v=\frac {24000}{1200}=20 m/s[/tex]
