Given:
Velocity = 80 m/s
Momentum = 850 kg.m/s
Let's find the mass of the body.
Apply the formula:
[tex]\rho=mv[/tex]Where:
p is the momentum
m is the mass
v is the velocity.
Rewrite the formula for mass, m
[tex]m=\frac{\rho}{v}[/tex]Thus, we have:
[tex]\begin{gathered} m=\frac{850}{80} \\ \\ m=10.625\text{ kg} \end{gathered}[/tex]The mass of the body is 10.625 kg.
ANSWER:
1.) 10.625 kg
