1. The problem statement, all variables and given/known data I do not know if this is the correct forum to post this in but here goes. I got all of the answers correct, but I just have a question on part F. 1.) The figure shows a motion diagram of a particle in circular motion at a constant speed. The axes have units of meters. Each dot represents a 5 second time interval. a) Write out the displacement vector from point 1 to point 2 in component form b) Write out the displacement vector from point 1 to point 2 as a magnitude and angle from horizontal. c) What is the speed of the particle? To do this, determine a velocity vector and take its magnitude. d) Use graphical vector addition to show the direction of the acceleration at points 1 and 3. You can do this right on the figure or on another sheet of paper. e) From your answer in part d, find the magnitude of the acceleration at point 3. Remember a = ΔV/Δt f) Compare your answer from part e to the result from aradial = v2tan/r 3. The attempt at a solution Just to show you that I actually did the work, here are the answers I got. A) -7i+3j B) 7.61m at 23.2° above the -x axis. C) 1.52 m/s D) I drew the acceleration vector on my paper. E) 0.226 m/s/s F) 0.231 m/s/s My question to you is why are the answers for Part E and Part F different? They are both correct (as calculated in the problems) and both describe the magnitude of the same acceleration vector. Any and all help would be appreciated!
