Please help me with these questions !!!

2. (08.03, {13.04 Hc) For the regions bounded by}: = trace): and 4 PartA: Find the limits of integration. ('I 0 points) Part B: Write the expression representing the total area. ('i 0 points} Part c: Solve for the total area. (10 points} 1. (08.01 HC) A yo-yo is moving up and down a string so that its velocity at time t is given by v(t) = 4cos(t) for time t 2 0. The initial position of the yo-yo at time t = 0 is x = 4. 0 , N/a Part A: Find the average value of v(t) on the interval (10 points) Part B: What is the displacement of the yo-yo from time t = 0 to time t = n? (10 points) Part C: Find the total distance the yo-yo travels from time t = 0 to time t = it. (10 points)
