Question

A car is traveling in a race. The car went from the initial velocity of 36 m/s to the final velocity of 65 m/s in 5 seconds. What is the acceleration?

Answer 1

Assuming the car's acceleration was constant throughout the 5 second interval, it would be equal to its average acceleration:

`a=a_(\rm avg)=(65\,(\rm m)/(\rm s)-36\,(\rm m)/(\rm s))/(5\,\rm s)=5.8\,(\rm m)/(\mathrm s^2)`
