A swimmer, capable of swimming at a speed of 1.89 m/s in still water (i. e., the swimmer can swim with a speed of 1.89 m/s relative to the water), starts to swim directly across a 2.67-km-wide river. However, the current is 1.20 m/s, and it carries the swimmer downstream. (a) How long does it take the swimmer to cross the river? (b) How far downstream will the swimmer be upon reaching the other side of the river?

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
