Karen lives 500 m from school travels to school in straight line.

Starts out at time zero at rest and accelereates towards school with an acceleration of 2.0 m/s2 for 10 seconds. she then travels at constant speed for 5 seconds.

she then slams on the brakes, coming to stop in 4 seconds.

she throws her car in reverse accelereating back home at 5 m/s2 for 3 seconds and then travelling at constant speed for 4 seconds. and then slowing at constant acceleration to stop back at home

she spends 20 seconds at home

then she accelerates at 8 m/s2 for 3 seconds then travels to within 50 m of the school (which is 450 m) and slows to a stop at constant acceleration.

QUESTION: Draw careful x-t,v-t and a-t graphs with all value calculated.

2. The attempt at a solution

I've attached an excel document of my attempt at it. I basically recored the time known as well as its position/velocity/ or accel that was given in the problem. I don't really know how to fil in the blanks tho, and i'm not even sure if my timings are right.

i also drew out the scenerio too but i can't scan it in.
