Atennis ball connected to a string is spun around in a vertical, circular path at a uniform speed. the ball has a mass m = 0.158 kg and moves at v = 5.22 m/s. the circular path has a radius of r = 1.1 m 1) what is the magnitude of the tension in the string when the ball is at the bottom of the circle? 2) what is the magnitude of the tension in the string when the ball is at the side of the circle? . 3) what is the magnitude of the tension in the string when the ball is at the top of the circle? 4) what is the minimum velocity so the string will not go slack as the ball moves around the circle?

The temperature at a point (x, y) is t(x, y), measured in degrees celsius. a bug crawls so that its position after t seconds is given by x = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)
