For the child walking on the merry-go-round shown below, with a constant speed u 2 ft/s and constant angular velocity of the merry-go-round of w 25 rpm. Assuming the child starts at the center at t 0 sec. and walks in a straight line towards the outside:
a. Calculate the velocity components at t 3.5 sec.
b. Calculate the acceleration components at t 3.5 sec making sure to label each
