A 0.14 kg sphere hangs on a string from the ceiling of a car that is accelerating horizontally at a constant rate. The sting makes an angle of 22o with the vertical. To a person sitting inside the car, the sphere appears motionless. (the angle between the sphere and the vertical is constant)
1) What is the tension in the string?
2) What is the magnitude of the net force on the sphere?
3) What is the magnitude of the acceleration of the car?
