Which of the following represents a case in which you are not accelerating? View Available Hint(s) Which of the following represents a case in which you are not accelerating? Driving 60 miles per hour around a curve Going from 0 to 60 miles per hour in 10 seconds Slamming on the brakes to come to a stop at a stop sign Driving in a straight line at 60 miles per hour

Answer 1

Answer:

4) Driving in a straight line at 60 miles per hour

Explanation:

1) Driving 60 miles per hour around a curve

2) Going from 0 to 60 miles per hour in 10 seconds

3) Slamming on the brakes to come to a stop at a stop sign

4) Driving in a straight line at 60 miles per hour

1) The speed is constant here, but in circular motion you have an acceleration that is v^2/r, where v is the speed and r the radius

2) You are accelerating from 0 to 60

3) You are desaccelerating

4) constant speed , no acceleration
