Physics
Instead of moving back and forth, a conical pendulum moves in a circle at constant speed as its string traces out a cone (see figure below). One such pendulum is constructed with a string of length L = 12.5 cm ? = 8.48°
(a) What is the radial acceleration of the bob?
| magnitude | m/s2 |
| direction |
(b) What are the horizontal and vertical components of the tension force exerted by the string on the bob? (Assume radially inward to be the positive x axis and vertically upward to be the positive y axis. Express your answer in vector form.)

3. CONICAL PENDULUM A conical pendulum is a piece of physics apparatus in which a massive bob, connected to a string (which also connects to the ceiling) swings around in a horizontal circle. The string traces out the surface of a cone, thus the name conical pendulum. See: Ihttps://www.youtube.com/watch?v 3Tf9xXsgqD4. The bob has mass m, the string length is L and the circle has radius R. Find expressions for the following in terms of the given quantities, and g a)...

The figure below shows a "conical pendulum", in which the bob
(the small object at the lower end of the cord) moves in a
horizontal circle at constant speed. (The cord sweeps out a cone as
the bob rotates.) The bob has a mass of 0.050 kg, the string has
length L = 0.66 m and negligible mass, and the bob follows a
circular path of circumference 0.86 m.

You make a conical pendulum (Figure 1) using a string of length 0.800 m and a bob of mass 0.150 kg. When the bob is moving in a circle at a constant speed, the string is at an angle of 30.0 ∘ from the vertical. Express your answers with the appropriate units. a) What is the radius of the circle around which the bob moves? b) How much time does it take the bob to complete one circle? c) What...

Question 3 The figure shows a conical pendulum, in which the bob (the small object at the lower end of the cord) moves in a horizontal circle at constant speed. (The cord sweeps out a cone as the bob rotates.) The bob has a mass of 0.035 kg, the string has length L = 1.1 m and negligible mass, and the bob follows a circular path of circumference 0.76 m. What are (a) the tension in the string and (b)...

Consider a conical pendulum with a bob of mass m = 75.0 kg on a string of length L = 10.0 m that makes an angle of 0 = 7.00° with the vertical. (Consider +î to be towards the center of the circular path and +ġ to be upward.) m (a) Determine the horizontal and vertical components of the force exerted by the string on the pendulum.

A bob of mass m = 0.300 kg is suspended from a fixed point with a massless string of length L = 23.0 cm . You will investigate the motion in which the string traces a conical surface with half-angle θ = 15.0 ∘. What tangential speed v must the bob have so that it moves in a horizontal circle with the string making an angle 15.0 ∘ with the vertical?

A bob of mass m = 0.250 kg is suspended from a fixed point with a massless string of length L = 21.0 cm . You will investigate the motion in which the string traces a conical surface with half-angle θ = 25.0 ∘. What tangential speed v must the bob have so that it moves in a horizontal circle with the string making an angle 25.0 ∘ with the vertical? Express your answer numerically in meters per second.

A pendulum is 0.864 m long and the bob has a mass of 1.04 kg. When the string makes an angle of θ= 14.8 degrees with the vertical, the bob is moving at 1.44 m/s. Find the tangential and radial acceleration components and the tension in the string. (Hint: Draw an FBD for the bob. Choose the x-axis to be tangential to the motion of the bob and the y-axis to be radial. Apply Newton's second law.) at = ______...
