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 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.
s"in all problems 2.) A small sphere hangs from a string attached to the ceiling of a uniformly accelerating train car. It is observed that the string makes an angle of 37 with respect to the vertical. The magnitude of the acceleration a of the train car is most nearly (A) 60 m/s (B) 7.5 m/s (C) 8.0 m/s (D) 10 m/s (E) 13 m/s
A small ball (mass 0.3kg) hangs from the ceiling of a car at the end of a 30cm long string (but the string itself is essentially massless). When the car accelerates, the ball moves toward the back of the car and the string makes an angle θ=14∘ with the vertical, as shown in the figure. What is the magnitude of the car's acceleration
An object of mass m = 0.300 kg is suspended from the ceiling of an accelerating truck as in the figure below. Take a = 2.80 m/s2. A truck is accelerating to the right, as indicated by an arrow labeled vector a. A small sphere of mass m is suspended from the ceiling of the truck by a string. The string makes an angle θ with the vertical, and the mass hangs to the left of the vertical. (a) Find...

A pendulum consists of a small object hanging from the ceiling at the end of a string of negligible mass. The string has a length of 0.79 m. With the string hanging vertically, the object is given an initial velocity of 2.1 m/s parallel to the ground and swings upward in a circular arc. Eventually, the object comes to a momentary halt at a point where the string makes an angle θ with its initial vertical orientation and then...
A horizontal wire is hung from the ceiling of a room by two massless strings. The wire has a length of 0.22 m and a mass of 0.084 kg. A uniform magnetic field of magnitude 0.060 T is directed from the ceiling to the floor. When a current I exists in the wire, the wire swings upward and, at equilibrium, makes an angle 55 degrees with respect to the vertical. Find the current I.
A pendulum consists of a small object hanging from the ceiling at the end of a string of negligible mass. The string has a length of 0.71 m. With the string hanging vertically, the object is given an initial velocity of 1.6 m/s parallel to the ground and swings upward in a circular arc. Eventually, the object comes to a momentary halt at a point where the string makes an angle θ with its initial vertical orientation and then swings...
1. A horizontal wire is hung from the ceiling of a room by two massless strings. The wire has a length of 0.11 m and a mass of 0.005 kg. A uniform magnetic field of magnitude 0.055 T is directed from the ceiling to the floor. When a current of I = 34 A exists in the wire, the wire swings upward and, at equilibrium, makes an angle φ with respect to the vertical, as the drawing shows. Find (a)...
