The car is moving along the road. The time dependence of the speed is described by the equation V = 2 + t. Determine the path traveled by the car in 1 minute.

V (t) = 2 + t.

t = 1 min = 60 s.

S -?

With uniformly accelerated motion, the speed of the body V (t) changes according to the formula: V (t) = V0 + a * t, where V0 is the initial speed of the body, and is the acceleration during motion.

For the dependence V (t) = 2 + t, the initial velocity is V0 = 2 m / s, the acceleration of the body is a = 1 m / s2.

The path of the body at uniformly accelerated motion is determined by the formula: S = x – x0, where x is the coordinate of the body at time t, x0 is the initial coordinate of the body.

x (t) = x0 + V0 * t + a * t ^ 2/2.

S = x0 + V0 * t + a * t ^ 2/2 – x0 = V0 * t + a * t ^ 2/2.

S = 2 * t + t ^ 2/2.

S = 2 * 60 s + 1 m / s2 * (60 s) ^ 2/2 = 1920 m.

Answer: the car has traveled the path S = 1920 m.
