1. A block is hung by a string from the inside roof of a van. When the van goes straight ahead at a speed of 21.5 m/s, the block hangs vertically down. But when the van maintains this same speed around an unbanked curve (radius = 111 m), the block swings toward the outside of the curve. Then the string makes an angle x with the vertical. Find θ.
2. centripetal acceleration Ac = v^2 /r
normal force Fn= mg
i then worked out that the sin x = Ac/Fn
I think these should all be right
3. Ac = 4.164 N
And then sin x = Ac/Fn, but I have no idea where to go from here or even if I am on the right path
