Question

A car traveling initially at 8.34 m/s accelerates at the rate of 0.993 m/s 2 for 3.91 s. What is its velocity at the end of the acceleration? Answer in units of m/s. *40 POINTS*

Answer 1

velocity = initial velocity + (acceleration)(elapsed time)

              =  8.34 m/s       +   (0.993 m/(sec)^2 ) * 3.91 sec  12.22 m/s
