(b) Calculate by hand graphically and numerically the x and y components of the velocity of the object for your instant. (c) Calculate the normal component of the acceleration for your instant. Use this and the supplied x component to draw the acceleration vector. Calculate the y and tangential components. Is the motion speeding up or slowing? (d) Calculate by hand graphically and numerically the r and 0 components of the velocity for your instant. (e) Calculate by hand graphically and numerically the r and e components of the acceleration for your instant. (f) Calculate r,i,ï,0,ð and ë relative to the origin for your instant. Include units and directions as appropriate. Summarize your results in a table.
