A pendulum swinging in a circular arc under the influence of gravity, as shown in the figure, has both centripetal and tangential components of acceleration. length of pendulum is 0.75 m
a) If the pendulum bob has a speed of 2.7 m/s when the cord makes an angle of θ = 17 with the vertical, what are the magnitudes of the components at this time? Express your answers using two significant figures separated by a comma.
b) Where is the centripetal acceleration a maximum?
c) What is the value of the tangential acceleration at that location?

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 = ______...

1) A pendulum bob of mass m is attached to an ideal string of length L. The other end of the string is attached to a rigid hook. The bob is lifted along a circular are of radius L until it and the string makes an angle with the vertical, as shown. The bob is then released from rest. a) Prediction: If the magnitude of the tension in the string is measured to...

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 bob of mass m is suspended from a fixed point with a massless string of length L (i.e., it is a pendulum). You are to investigate the motion in which the string moves in a cone with half-angle θ. 1. What tangential speed, v, must the bob have so that it moves in a horizontal circle with the string always making an angle θ from the vertical? Express your answer in terms of some or all of the variables...
