A block is hung by a string from the inside roof of a van. When the van goes straight ahead at a speed of 29 m/s, the block hangs vertically down. But when the van maintains this same speed around an unbanked curve (radius = 135 m), the block swings toward the outside of the curve. Then the string makes an angle θ with the vertical. Find θ

    tanTheta= centripetal acceleration/g

    centripetal acceleration= v^2/r
    solve for theta.
