A ball is attached to a horizontal cord of length l whose other end is fixed. (a) If the ball is released, what will be its speed at the lowest point of its path? (b) A peg is located a distance h directly below the point of attachment of the cord. If h=0.75l , what will be the speed of the ball when it reaches the top of its circular path about the peg?

If a flag staff subtends the same angles at the points A,B,C and D on the horizontal plane through its foot, the points A,B,C and D from a

A series of pulses, each of amplitude 0.150 m , are sent on a string that is attached to a wall at one end. The pulses are reflected at the wall and travel back along the string without loss of amplitude. When two waves are present on the same string. The net displacement of a given point is the sum of the displacement of the individuals waves at the point. What is the net displacement at point on the spring where two pulses am crossing, (a) if the string is rigidly attached to the post? (b) if the end at which reflection occurs is free is slide up and down ?
