Answer:
The mass of a person walking west at a speed of 0.8 m/s with a momentum of 52.0 kg•m/s west is 65 kg.
Explanation:
The linear momentum of a particle of mass m or body m that moves with a velocity v is defined as the product of mass by velocity
P = m * v
Where, as previously stated,
- P = momentum
- m is the mass of the body
- v is the velocity.
The units in the SI (International System) are N*s ([tex]kg*\frac{m}{s}[/tex])
Then, the mass of a person, knowing the speed and momentum, can be calculated as:
[tex]m=\frac{P}{v}[/tex]
In this case=
[tex]m=\frac{52 kg*\frac{m}{s} }{0.8 \frac{m}{s} }[/tex]
m= 65 kg
Then, the mass of a person walking west at a speed of 0.8 m/s with a momentum of 52.0 kg•m/s west is 65 kg.
