The movement of a truck is given by the equation x = 380-20t. To determine the initial coordinate and speed of the car. At what point in time the car will be at a point with a coordinate of 200m
The initial coordinate is 380 m, the vehicle speed is 20 m / s.
Let’s determine when the car gets to the point with the coordinate x = 200:
x = 380 – 20 * t = 200,
20 * t = 380 – 200 = 180, whence t = 9 s.
Answer: the car will get to the specified coordinate in 9 seconds after the start of movement.
