A simple pendalum is suspended from a peg on a verticle wall . The pendulum is pulled away from the well is a horizental position (see fig) and released . The bell his the well the coefficient of resitution being `(2)/(sqrt(5)`

what is the miximum number of colision after which the amplitube of secillections between less that `60` digree ?

A simple pendulum is supended from a peg on a verticl wall. The pendulum is pulled away from the wall to a horizontal position and releases as shown in figure -4.152. The ball hits the wall, the coefficient of restitution being 2//sqrt2. What is the minimum number of collisions after which the amplitude of oscillation becomes less than 60^(@)

A simple pendulum is suspended from a peg on a wall which is inclined at an angle of 30^(@) with the vertical. The pendulum is pulled away from the wall to a horizontal position (with string just taut) and released. The bob repeatedly bounces off the wall, the coefficient of restitution being e = (2)/(sqrt(5)) Find the number of collisions of the bob with the wall, after which the amplitude of oscillation (meaured from the wall) becomes less than 30^(@)

A simple pendulum is hanging from a peginserted in a vertical wall. Its bob is strteched to horizontal position form wall and left freee to move, the bob hits the wall. If coefficient of restitution is (2)/(sqrt(5)) . After how many collisions the amplitude of vibration will becomes less then 60^(@) .

A simple pendulum is hanging from a peg inserted in a vertical wall. Its bob is stretched in horizontal position from the wall and is left free to move. The bob hits on the wall the coefficient of restitution After how many collsions the amplitude of vibration will become less than 60 ^(@)

Two identical simple pendulums A and B are fixed at same point. They are displaced by very small angles alpha " and " beta ( = 2 alpha) respectively and are simultaneously released from rest at time t = 0. Collisions between the pendulum bobs are elastic and length of each pendulum is l. (a) What is the minimum number of collisions between the bobs after which the pendulum B will again reach its original position from where it was released ? (b) Find the time (t) at which B reaches its initial position for the first time after the release. (c) Write the kinetic energy of pendulum B just after n^(th) collision? Take mass of each bob to be m.
