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.

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 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

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...

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...

Problem 4 Two identical small spheres with mass, m, are hung from a very thin string of length L, as shown in figure (17.56). The radius of the spheres is small and we can treat the spheres as point like objects. The charge on each sphere is q. Determine the angle, θ, each string makes with the vertical direction. Assume that the angle is small, (Hint: when θ is small you can use that θ sin θ tan θ) mass...

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.

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)...
