A block is hung by a string from the inside roof of a van. When the van goes straight ahead at a speed of 24.0 m/s, the block hangs vertically down. Butwhen the van maintains this same speed around an unbanked curve (radius = 158 m), the block swings toward the outside of the curve. Then the string makes an angle 9 with the vertical. Find 6.
