1. A pendulum consists of a small object called a bob hanging from alight cord of fixed length, with the top end of the cord fixed, asshown in the figure. The bob moves from its turning point A,through point B, to the lowest point in its trajectory at C, where ithas its maximum speed. Assume the pendulum moves withoutfriction, swinging equally high on both sides. a) Calculate the radialcomponent of the bob's acceleration at Point A. b) Calculate the Ac)Btangential component of the bob’s acceleration at point C?Roughly what is the direction of the bob's acceleration at point B?C

A comet is in an elliptical orbit around the Sun. Its closest approach to the Sun is a distance of 4.9 × 1010 m (inside the orbit of Mercury), at which point its speed is 8.9 x 104 m/s. Its farthest distance from the Sun is far beyond the orbit of Pluto. What is its speed when it is 6 x 10¹2 m from the Sun? (This is the approximate distance of Pluto from the Sun.) speed= m/s
Mary and her younger brother Alex decide to ride the 26 ft diameter carousel at the State Fair. Mary sits on one of the horses in the outer section at a distance of 11 feet from the center. Alex decides to play it safe and chooses to sit in the inner section at a distance of 6 feet from the center. What is Mary's centripetal acceleration aM compared to that of Alex's centripetal acceleration aA? Give your answer as a multiple of aA.
For the normal force in the drawing to have the same magnitude at all points on the vertical track, the stunt driver must adjust the speed to be different at different points. Suppose, for example, that the track has a radius of 2.24 m and that the driver goes past point 1 at the bottom with a speed of 28.3 m/s. What speed must she have at point 3, so that the normal force at the top has the same magnitude as it did at the bottom?
QUESTION 1 A boy takes a 2.0-kg rock and ties it to the end of a light, uniform, 0.80-m-long rope. He then grabs the other end of the rope and swings the rock in a vertical circle.

A light rod is 88 cm long. Its top end is pivoted on a low-friction horizontal axle. The rod hangs straight down at rest with a small massive ball attached to its bottom end.

You have hung a 0.500 kg mass from the end of a 1.00 m long pendulum and suspended it from the end of a force sensor so that it is at equilibrium. You tare the force sensor. You then set the pendulum in motion. At the bottom of the motion, the sensor reads -1.96 N. What is the magnitude of the centripetal force, in N?

Tidal forces are gravitational forces exerted on different parts of a object by a second object. Their effects are particularly visible on Earth's surface in the form of tides. To understand the origin of tidal forces, consider Earth-Moon system to consist of two spherical bodies, each with a spherical mass distribution. Let RE be the radius of Earth, m be the mass of the Moon, and G be the gravitational constant. Part B Since the gravitational force between two bodies decreses with distance, the accelaeration a(near) experienced by a unit mass located at the point on the earth's surface closest to moon is slightly different from the acceleration a(far) experienced by a unit mass located at the point on the earth`s surface farthest from the moon. Give a general expresion for the quantity a(near)- a(far).
