What is the mass of a car moving under braking with an acceleration of 1.5 m / s if the force acting on it is 4.5 kn?
| September 29, 2021 | education
These tasks: a (acceleration of a given vehicle during braking) = 1.5 m / s; F (acting force (resistance force)) = 4.5 kN (4.5 * 10 ^ 3 N).
The desired mass of a given vehicle is determined by the formula: m = F / a.
Let’s perform the calculation: m = 4.5 * 10 ^ 3 / 1.5 = 3 * 10 ^ 3 kg (3 tons).
Answer: The given vehicle has a mass of 3 tons.
