Find the mass of a body that moves at a speed of 0.2 m / s. The momentum of the body is 2 kg m / s.

From the formula for calculating the momentum of a body, equal to the product of body weight by its speed, p = m * V, we express the body mass.
It will be calculated using the following formula: m = p / V.
We have all the necessary data for the calculation: body impulse p = 2 kg * m / s, body speed V = 0.2 m / s. We substitute the data into the formula and calculate the body weight.
m = 2 (kg * m / s) / 0.2 m / s = 10 kg.
Answer: Body weight is 10 kilograms.
