A block is hung by a string from the inside roof of a van. When the van goes straight ahead at a speed of 33 m/s, the block hangs vertically down. But when the van maintains this same speed around an unbanked curve (radius = 140 m), the block swings toward the outside of the curve. Then the string makes an angle with the vertical. Find the angle.

Solution Summary

The solution shows how to find the angle of the string with the vertical when the van travels on an unbanked curve.

Solution Preview

The block is experiencing two forces as the van travels around the curve. The first is the force of gravity in a downwards direction and the other is the ...
