A small object hangs from a string attached to the rearview mirror of your car that is accelerating at a rate of ax = 1.10 m/s2. (Consider a tension in the string T, a weight of the object W, and an angle 0 that the string makes with the vertical.) Coordinate system: +x is right; +y is up. Let's trace all forces acting on this object before finding the angle 0 the string makes with respect to the vertical. (0 means the theta symbol)!     

1) What is the magnitude of the tension in the string in the x-direction (Tx)?

Group of answer choices:

A) Tarctan0

B) Tcos0
