The trolley moves from rest with an acceleration of 0.25m / s ^ 2. How far will the trolley be in 20s?

Initial data: a (acceleration with which the trolley began to move) = 0.25 m / s ^ 2; t (trolley travel time) = 20 s; V0 (initial trolley speed) = 0 m / s.

The distance that the trolley will cover in 20 seconds is calculated using the formula: S = V0 * t + 0.5 * a * t ^ 2 = 0 + 0.5 * a * t ^ 2 = 0.5 * a * t ^ 2 …

Let’s perform the calculation: S = 0.5 * 0.25 * 20 ^ 2 = 0.5 * 0.25 * 400 = 50 m.

Answer: After 20 seconds, the trolley will be at a distance of 50 meters from the starting point.
