First you need to convert 5 km / h to m / s (SI system). To do this, you need to divide 5 by 3600, and then multiply by 1000. Rounding up, it turns out 1.39 m / s.
Formula for finding the momentum p = mU. p – momentum, m – mass, U – velocity. Substituting the numbers in the formula, we get 50 × 1.39 = 69.5kg × m / s.
Answer: 69.5 kg × m / s
