Question

2. (a) A Go-Round rotates at 0 0.105 rad/s (see Seminar Problem 2), and a person's position (in metres) is given by: r (5.00 -0.75t)e, m Calculate the person's acceleration as a vector at 1.5 s in the plane polar (i.e., er and ee) coordinate system. Also determine the magnitude of the acceleration. (b) Consider the same Merry-Go-Round, but this time it starts from rest and has a constant angular acceleration, o 5.00x10 2 rads The person's position is given again by r (5.00 -0.75)er m Calculate the person's acceleration as a vector and as magnitude at 1.50 s in the plane polar coordinate system. [Note that the angular velocity at instant t is given by é ao at, where a) is the initial an velocity Assume 0 for this problem.]
