Answer to Question #348589 in Atomic and Nuclear Physics for erika miguel

Question

I. COMPUTATION

1. The momentum of a particle is 50 kg-m/s. If the velocity of the particle is 5 m/s, what is its mass? If the particle is located on a certain planet where the acceleration due to gravity is 5.87 m/s², what is its weight?

Answer 1

The mass of the particle

$$m=\frac{p}{v}=\rm\frac{50\: kg\cdot m/s}{5\: m/s}=10\: kg$$

The weight of the particle

$$W=mg=\rm 10\: kg*5.87\: m/s^2=58.7\: N$$
