The body begins to move in a straight line at a speed of 2 m / s and in 10 seconds increases

The body begins to move in a straight line at a speed of 2 m / s and in 10 seconds increases the speed to 7 m / s. what is acceleration?

Given:

v0 = 2 m / s (meters per second) – the initial speed of the body;

v1 = 7 m / s is the speed of the body through the time interval t;

t = 10 seconds – time span.

It is required to determine a (meter per second squared) – the acceleration of the body.

To determine the acceleration of a body, you need to use the following formula:

a = dv / t = (v1 – v0) / t;

a = (7 – 2) / 10 = 5/10 = 1/2 = 0.5 m / s2.

Answer: the acceleration of the body is 0.5 m / s2.
