What is the acceleration modulus of a car, which, moving from a state of rest, during the time interval delta t = 7.5

What is the acceleration modulus of a car, which, moving from a state of rest, during the time interval delta t = 7.5 seconds, gained speed, the modulus of which is v = 15 M / S.

Given:

V0 = 0 meters per second – the car started moving from a state of rest;

V1 = 15 meters per second – vehicle speed in time t after the start of movement;

t = 7.5 seconds – time span.

It is required to determine the vehicle acceleration a (m / s ^ 2).

To find the acceleration of a car, you need to use the following formula:

a = (V1 – V0) / t = (15 – 0) / 7.5 = 15 / 7.5 = 2 m / s ^ 2.

Answer: The acceleration of a car is 2 meters per second squared.
