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...
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...
9. A ball of mass m- 30 g that is attached to the ceiling by a light string is swinging around in a circle in the xy-plane, as shown. The string makes an angle θ-30° with the vertical. The length of the string is r- 40 cm. What is the magnitude of the torque on the ball about the fixed end of the string due to gravity? a) 0.0402 mN b) 0.0588 m N c) 0.0633 m N 0.0675 mN...
1. Hanging from the rear view mirror of your car is a plastic soccer ball. The ball is hanging from 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° a (a) (5 points) Illustrate and fully label the situation described above. (b) (5 points) Construct and fully label the necessary FBD to help solve the problem. (c) (10 points) Determine the radius...
