The trolleybus starts to move with an acceleration of 1.2 m / s2. What speed does a trolleybus get in 1 minute?

The formula by which you can calculate the speed of the trolleybus:

V = V0 + a * t, where V0 is the initial speed of the trolleybus (the trolleybus got under way and V0 = 0 m / s), t is the trolleybus movement time (t = 1 min = 60 s), and is the constant acceleration of the trolleybus (a = 1.2 m / s²).

Let’s calculate the speed acquired by the trolleybus:

V = V0 + a * t = 0 + 1.2 * 60 = 72 m / s.

Answer: The trolleybus has reached a speed of 72 m / s.
