If, with uniformly accelerated movement, the speed of the body in 2 sec. changed by 4 m / s

If, with uniformly accelerated movement, the speed of the body in 2 sec. changed by 4 m / s then over the next 3 s. will she change to?

Initial data: t1 (first time of motion of the considered body) = 2 s; ΔV1 (speed change during t1) = 4 m / s; t2 (second time of body movement) = 3 s; the movement is uniformly accelerated.

The change in body speed over the next 3 seconds can be determined by the formula: ΔV2 = V – ΔV1 = ΔV1 + a * t2 – ΔV1 = a * t2 = ΔV1 / t1 * t2.

Let’s calculate: ΔV2 = 4/2 * 3 = 6 m / s.

Answer: Over the next 3 seconds, the body’s speed will change by 6 m / s.
