A train is passing by and you notice a ball is hanging from the ceiling. You...
8) Shown in the diagram is a lightbulb attached to a string, hanging from the ceiling of an accelerating train car. The string supporting the bulb makes an angle 6-25 with the vertical. What is the direction and magnitude of the car's acceleration? Wİ
A .5 kg ball is suspended from a ceiling by two strings. The ball is at rest String 1 on the left makes a 30 degree angle with the vertical. String 2 on the right makes a 60 degree angle with the vertical What is the magnitude of String 1 compared to String 2 Explain rationale for this answer. Suppose the ceiling is an elevator moving downward with a speed of 2m/s How does tension in string 1 compare to...
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) Tetherball is a game that uses a ball hanging from a string attached to the top of a post, where the ball is sent flying around in the tangential direction. Assume a uniform gravitational acceleration g pointed downward. This is an example of what is known as a “conical pendulum.” i) Find the equilibrium angle that the string makes with the vertical for a given speed v such that the ball traces a circle at uniform height. ii) Estimate...
9) A ball of mass m is attached to the ceiling via a string of length L. The ball is given a push to set it in motion. The ball then travels in a horizontal circle, such that the string makes and angle 0 with the vertical. It is observed that it takes time T for the ball to make one complete revolution. How can this experiment be used to measure the magnitude of the gravitational acceleration g. problem 9...
1. Hanging from the rear view mirror of your car is a plastic soccer ball. The ball is hanging from a single, massless string. While making a right turn at 45 mph you notice that the angle the ball and string make from the vertical is precisely 33 degrees. (a) Illustrate and fully label the situation described above. (b) Construct and fully label the necessary FBD (full body diagram) to help solve the problem. (c) Determine the radius of the...
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 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
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...
