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) Calculate at what angle to the vertical will thetension in the string be twice the weight of the dice?
