The car, the speed of which is 10m / s, began to accelerate with a constant acceleration

The car, the speed of which is 10m / s, began to accelerate with a constant acceleration of 0.5m / s2. what is the speed of the car 20 seconds after it began to accelerate?

v0 = 10 meters / second – initial vehicle speed;

a = 0.5 m / s2 – vehicle acceleration;

t = 20 seconds – time span.

It is required to determine v (m / s) – the speed of the car after a time interval t.

According to the problem, the car began to accelerate with constant acceleration. Then, to determine the speed, you need to use the following formula:

v = v0 + a * t;

v = 10 + 0.5 * 20;

v = 10 + 10;

v = 20 meters / second.

Answer: After 20 seconds, the vehicle speed will be 20 meters / second.
