A race car traveling at 44 m/s is accelerated to a velocity of 22 m/s over an 11 s interval. What is the displacement of this time? (Could you show how you got the answer?) Thank you
Actually the car is decelerating. The average velocity during the interval is (22 + 44)/2 = 33 m/s.
Multiply that by 11 s for the distance covered. Looks like 363 m.
