| 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.
Given:
V = 2 + t
t = 1 min = 60 sec
S -?
The equation of the dependence of the speed on time V = 2 + t corresponds to the formula
uniformly accelerated speed: V = V0 + a * t,
from this formula it follows that the initial velocity V0 = 2 m / s, and the acceleration a = 1 m / s ^ 2
For uniformly accelerated motion, the path formula: S = V0 * t + a * t ^ 2/2
S = 2 * 60 + 1 * 60 ^ 2/2 = 120 + 1800 = 1920 m
