Homework SourseA pendulum consists of a small object hanging from the ceili
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 1.1 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 ? with its initial vertical orientation and then swings back downward. Find the angle ?.

Chapter 07, Problem 25 Your answer is partially correct. Try again focus on Conceets By accident, a large plate is dropped and breaks into three pieces. The pieces fly apart parallel to the floor. As the plate falls, its momentum has only a vertical component, and no component parallel to the floor. After the collision, the component of the total momentum parallel to the floor must remain zero, since the net external force acting on the plate has no component parallel to the floor.

let the pendulum attain a vertical height of h meter
=>By the law of energy conservation:-
=>PE(final) = KE(initial)
=>mgh = 1//2mv^2
=>h = v^2/2g = (1.1)^2/(2 x 9.8) = 6.1734 x 10^-2 m
Now by h = L - Lcos
=>6.1734 x 10^-2 = 0.71 (1 - cos)
=>1 - cos = 0.0869
=>cos = 0.913 =
=> = 24.06
