How fast can a pedestrian with a mass of 80 kg move so that his impulse is equal to that of a car with a mass of 2 tons, whose speed is 0.1 m / s.
To find the speed, we will equate these two impulses, but first we will translate 2 tons into kg, this is 2,000 kg
2,000 * 0.1 = 80 * V
200 = 80 * V
V = 200/80
V = 2.5 (m / s)
Answer: V = 2.5 (m / s)
