AP CALC AB :: WORKED OUT PROBLEMS :: PROBLEMS VI :: Please refer to the image below for a step-by-step work out of problems. We will go over it during next lunch tutoring session ::
1) The acceleration a(t) of a body moving in a straight line, in ft/sec^2 is given in terms of t by a(t)=5e^t-cos t/2. If at time t=0 seconds, the body is moving to the right at a speed of 3 ft/sec, and if s(t) is the distance of the body from the origin at s(2pi)-s(0)=___________.
2) A farmer has 160m of fence to enclose a rectangular area against a straight river. He only needs to fence in three sides. What is the maximum area that he can enclose with his materials. (ANSWERED IN SECOND IMAGE)
