If a car is traveling at a speed of 60 mi /hr, what constant (negative) acceleration will enable it to stop in 9 sec ?

Expert Answers

An illustration of the letter 'A' in a speech bubbles

For this we can use equations for motion.

V = at + V0

V  = final velocity

a  = accelaration

t  = time

V0= Initial velocity

 

For our question;

V  = 0 mi/s

a  = ????

t  = 9 s

V0= 60 mi/hr = 60/(3600) mi/s =...
