A block is hung by a string from the inside roof of a van. When the van goes straight ahead at a speed of 21.4 m/s, the block hangs vertically down. But when the van maintains this same speed around an unbanked curve (radius = 76.7 m), the block swings toward the outside of the curve. Then the string makes an angle θ with the vertical. Find θ.

A block is hung by a string from the inside roof of a van. What is the angle between the string and the vertical if the van travels A) Up an incline (15.0 ◦ away from the horizontal) at a constant speed B) On a straight, level road at constant acceleration of 5.00 m/s2 C) On an unbanked curve of radius 97.0 m at a speed of 23.0 m/s
A small sphere is hung by a string from the ceiling of a van. When the van is stationary, the sphere hangs vertically. However, when the van accelerates, the sphere swings backward so that the string makes an angle of θ with respect to the vertical. Find the acceleration of the van when θ = 11.4°.

A ball is attached to the end of a string hanging from the roof of a subway car. The train goes around a curve, turning to the left. You know that the car is traveling at 60 km/hr. • Which way will the ball appear to swing? Why? • If the ball swings at an angle of 15◦, what is the radius of curvature of the curve in the tracks
A block with mass m =7.5 kg is hung from a vertical spring. When
the mass hangs in equilibrium, the spring stretches x = 0.27 m.
While at this equilibrium position, the mass is then given an
initial push downward at v = 4.2 m/s. The block oscillates on the
spring without friction.
