Randomized Problem 3

course Phy 121

What are the average acceleration and final velocity of an object which accelerates uniformly from rest, traveling a distance of 69 cm from start to finish and ending up with a velocity of 18.1 cm/sec?

18.1cm/s=69cm/t

`ds / `dt is average velocity, not final velocity

T=3.8s

A=18.1/3.8=4.75m/s^2

Right idea throughout, but you need to find `dt based on average, not final, velocity.
