First define the region. Drawing a sketch chould help. 16 sin*theta = 4 when theta = arcsin 1/4 which cporresponds to 14.48 degrees and 165.52 degrees Your region is the area bounded by 16 sin(theta) on the outside and r = 4 on the inside. The outer curve is called a cardioid...

a) for the speed V, divide the arc length by the driving time, 38 s. b) The acceleration magnitude is V^2/R. It points to the center of the turn arc.

Construction: Make a perpendicular bisector (90 deg). Bisect that angle to get 45. Now you have one angle. For the 30 deg angle, set your compass to some arbitrary length. measure up the perpendiculare bisector that arbitrary length, mark that arc, and measure from that arc up...
