A trolleybus moving at a speed of 36 km / h stops when braking for 4 s. With what constant acceleration does it move when braking?
To find out the constant acceleration of the specified trolleybus during braking, we apply the formula: a = (Vн – 0) / t = Vн / t, where Vн – the speed of the specified trolleybus before braking (Vн = 36 km / h, which in the SI system is 10 m / with); t is the duration of the considered inhibition (t = 4 s).
Let’s perform the calculation: a = Vн / t = 10/4 = 2.5 m / s.
Answer: When braking, the specified trolleybus moved with an acceleration of 2.5 m / s.
