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.

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+atWhere,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 +a6.2a = 1.61 m/s².So, the constant acceleration of the body is 1.61m/s².To know more about acceleration, visit,https://brainly.com/question/460763#SPJ4
