A car weighing 1.5 tons when braking moves with an acceleration of 3 m / s2. What is the braking force?
| February 8, 2021 | education
Initial data: m (vehicle weight) = 1.5 t; a (vehicle acceleration modulus during braking) = 3 m / s ^ 2.
SI system: m = 1.5 t = 1.5 * 1000 kg = 1500 kg.
The braking force of a car can be determined using Newton’s second law: F = m * a.
Let’s do the calculation:
F = 1500 * 3 = 4500 N = 4.5 * 10 ^ 3 N = 4.5 kN.
Answer: The braking force is 4.5 kN.
