1. The problem statement, all variables and given/known data I have a graph where y-axis is displacement, x-axis as time, and rightward movement is positive. 3. The attempt at a solution A)The graph starts a 0m and moves with a positive slop until it hits 20m (takes 20sec) => This is rightward movement with +v? B) At 20m for about 20 seconds its a straight line (no slope) => Object is stationary? C) After 20 seconds (so we are at the 40sec mark on the x-axis) of been stationary it now moves with a slope that is negative until it hits the x-axis at 50seconds where displacement is 0m. => From that stationary point (at 20m) to the 0m the velocity is still positive and that it is now going LEFT? Also why is velocity 2m/s ([0-20]/2) instead of 0m/s, isn't the object back to where it started from? D)Now from that 0m it still continues until it hits -20m displacement.=> Velocity is negative and is it still moving to the left?
