A large wheel is attached to a boat and spins as the boat moves.A rock becomes nudged in the wheel as it spins in the water. It isnoticed that at t = 2 s, the rock is at the highest point 3 m abovethe water. At time t = 6 seconds, the rock is submerged in thewater 5 m below the water(the lowest point).
a. Graph 5 points to represent one cycle of the above problem.Label these points clearly on your graph.
b. Determine a cosine model to represent the motion of thewheel.
c. Determine whether the rock was above the water’s surface at t= 0 or below the water’s surface and how far is the rock above orbelow the water at this time?
