Your friend has a pair of fuzzy dice with a mass of 1.24 gram hanging from his rear-view mirror.
(a) When he accelerates from a stoplight, the dice deflect backward toward the rear of the car hanging at an angle of 6.28 degree relative to the vertical. Calculate the tension in the string holding the dice.
(b) Find at what angle to the vertical will the tension in the string be twice the weight of the dice?
