Select the statements that are true about tangents. Two concentric, noncongruent circles have a common tangent. Tangent lines make 90° angles with a radius of the circle. Common tangents can be tangent to two circles at the same time. A tangent touches the circle at just one point. S B

Q: Can this problem be reworked to find the correct speed of the curve?

A: Speed is the rate of change of position so, we get speed by differentiate r(t) with respect to t.
