A block is hung by a string from the inside roof of a car. When the car goes straight ahead at a speed of 29 m/s, the block hangs vertically down. But when the car maintains this equivalent speed around an unbanked curve (radius= 165 meter), the block swings toward the outside of the curve. Then the string makes an angle θ with the vertical. Compute the angle θ.
