Solution 1

The total momentum of a system is calculated by adding the momentum of each individual object in the system.

Momentum (p) is calculated by multiplying the mass (m) of an object by its velocity (v). This is represented by the formula p = m*v.

First, calculate the momentum of the first body: p1 = m1*v1 p1 = 2 kg * 2 m/s p1 = 4 kg.m/s

Next, calculate the momentum of the second body: p2 = m2*v2 p2 = 7 kg * 7 m/s p2 = 49 kg.m/s

Finally, add the momentum of the first body to the momentum of the second body to find the total momentum of the system: p_total = p1 + p2 p_total = 4 kg.m/s + 49 kg.m/s p_total = 53 kg.m/s

So, the total momentum of the system is 53 kg.m/s.

So, the total momentum of the system is 53 kg.m/s.
