Answer:
a. Momentum A = 280 Kgm/s.
b. Momentum B = 595 Kgm/s.
c. Total momentum = 875 Kgm/s.
Explanation:
Let the two people be A and B respectively.
<u>Given the following data;</u>
Mass A = 70kg
Mass B = 85kg
Velocity A = 4m/s
Velocity B = 7m/s
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
a. To find the momentum of A;
<em>Momentum A = 280 Kgm/s. </em>
b. To find the momentum of B;
<em>Momentum B = 595 Kgm/s.</em>
c. To find the total momentum of the two persons;
Substituting into the equation, we have;
<em>Total momentum = 875 Kgm/s</em>.
