A bat is 390 centimeters north of its cave. If the bat flies at a constant velocity of 260 centimeters per second to the south, how much time will the bat take to reach its cave?
Write your answer to the tenths place.

A2k pendulum has a speed of 1 m/s at a height of 1/2 meter

An athlete swings a ball, connected to the end of a chain, in a horizontal circle. the athlete is able to rotate the ball at the rate of 8.13 rev/s when the length of the chain is 0.600 m. when he increases the length to 0.900 m, he is able to rotate the ball only 6.04 rev/s. (a) which rate of rotation gives the greater speed for the ball? 6.04 rev/s 8.13 rev/s (b) what is the centripetal acceleration of the ball at 8.13 rev/s? m/s2 (c) what is the centripetal acceleration at 6.04 rev/s? m/s2
