What are the acceleration and final velocity of an object whose average velocity, accelerating uniformly from rest for 7.9 seconds, is 59 cm/s? How far does the object travel during the 7.9 seconds?
aVe=59cm/s t=7.9s
fVe=(fVe+0)/2=59cm/s=118cm/s
acc=118cm/s/7.9s=14.9cm/s^2
`ds=59cm/s*7.9s=46.61cm"
You multiplied wrong on that last one (59 cm/s * 7.9 s is a lot more than 46 cm), but your procedures and reasoning are all fine.
