| The truck began to move along a straight section of the highway with an acceleration of 2 m / s². The time of uniformly accelerated movement of the vehicle is 30 s. How far will the car move during this time?
The distance S that the car travels in time t with uniformly accelerated rectilinear movement is determined by the following formula:
S = v0 * t + a * t² / 2;
where v0 is the initial speed of the truck, a is its acceleration, and t is the time of uniformly accelerated movement.
Based on the conditions of the problem, the truck starts moving, which means that its initial speed is zero:
v0 = 0;
Also:
a = 2 m / s²;
t = 30s;
We get:
S = 2 * (30 ^ 2) / 2 = 900 (m);
Answer: the car will move 900 m.
