Answers to Practice Problems for Exam #1
... Consider the curve parametrized in polar coordinates as r = 5 sin(θ), θ = 2t. Express the velocity and acceleration vectors in terms of ur and uθ . Find the speed of the curve. Answer : One can, of course, use the formulas on page 655 of the book. Let’s do it by taking derivatives. If R is the posit ...

... Thus, in uniform circular motion there must be a net force to produce the centripetal acceleration. The centripetal force is the name given to the net force required to keep an object moving on a circular path. The direction of the centripetal force always points toward the center of the circle and ...
