a car accelerates from 12 m/sm/s to 22 m/sm/s in 6.2 ss . part a what was its acceleration assuming it is constant? express your answer using two significant figures.

Sagot :

The acceleration of the car is 1.61m/s and this is constant acceleration.

According to the equation of motion for constantly accelerating body,

V = U+at

Where,

V the final velocity which is 22m/s in our case.

U is the initial velocity which is 12m/s In our case.

T is the time taken which is 6.2 seconds in our case.

a is the acceleration of the body.

Now, putting all the values,

22 = 12 +a6.2

a = 1.61 m/s².

So, the constant acceleration of the body is 1.61m/s².
