Block swings toward the outside of the curve

Reference no: EM13646053

A block is hung by a string from the inside roof of a van. When the van goes straight ahead at a speed of 25 m/s, the block hangs vertically down. But when the van maintains this same speed around an unbanked curve (radius = 155 m), the block swings toward the outside of the curve. Then the string makes an angle θ with the vertical. Find θ.
