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
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...
physics 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 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)...
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 spherical insulator of mass 7.23 × 10-2 kg and charge +0.600 C is hung by a thin wire of negligible mass. A charge of -0.900 C is held 0.150 m away from the sphere and directly to the right of it, so the wire makes an angle with the vertical (see the drawing). Find (a) the angle and (b) the tension in the wire. Any help is appreciated A small spherical insulator of mass 7.23 x 102 kg...
A 14 mC charge is suspended vertically from a string connected to the ceiling. When a background electric field is set up in the area, it causes the mass to change position so that the string makes a 51 degree angle with the vertical. The electric field has two components, 108 N/C horizontally and 72 N/C vertically upward. What is the mass (in kg) of the charge?
8. A simple accelerometer can be made by suspending a small object from a string attached to a fixed point in an accelerating object - to the ceiling of a passenger car, for example. When there is an acceleration, the object will deflect, and the string will make some angle with the vertical. Find the acceleration of the object in terms of the angle the string makes to the vertical.
A van accelerates down a hill (see figure below), going from rest to 30.0 m/s in 5.30 s. During the acceleration, a toy (m = 0.210 kg) hangs by a string from the van's ceiling. The acceleration is such that the string remains perpendicular to the ceiling. a) Determine the angle b) Determine the tension in the string -
