Question 13 5 pts A CD has a mass of 25 grams and radius of 6.5cm. When it is inserted into a player, the CD starts from rest and is accelerated by a torque of 6 x 10'4Nm. Assuming the CD is a uniform solid disc, determine how long it takes the CD to reach an angular speed of 30 rad/s. Question 14 5 pts A pendulum clock can be approximated by a simple pendulum of length 1.150m and keeps accurate time at a location where g = 9.83 m/sz. In a location where g = 9.78 m/sz, what must be the new length of the pendulum such that the clock continues to keep accurate time (that is, its period remains the same)
