Homework Answers
Part A
Graph D is correct as drives moves in the east at constant direction.
Part B
Graph A is correct as the motion is now in negative direction
Part C
Graph F is fine.
Part D
Graph E is correct. see the direction of motion. He stops at stop sign where x = 0 then moves

Review | Constants A box of mass 11.3 kg tests on the flat bed of a truck the box is not tied down in any way. The coefficients of friction between the box and the flat bed are stops at a stop sign and then starts to move to the West with a carelessly large acceleration of 2.16 m/s 0.19 and juk = 0.16.
