Number 7 and 8 show all work by work

7) The figure below shows a conical pendulum. It consists of a bob is suspended at the end of a string and describes a horizontal circle at a constant speed of 1.28 m/s. If the length of the string is 1.20 m and it makes an angle of 20" with the vertical, find the acceleration of the bob. L 8) A stone moves in a circle of radius 60.0 cm and has a centripetal acceleration of 90 m/s. How long does it take to make 8 revolutions
