A student fixes two ends of a rope to two rigid supports A and B, placed at a distance of 15m. He then gives a transverse horizontal jerk to create a pulse in the rope which moves from A to B, B to A, repeatedly. The pulse dies after completing three, to and fro journeys from A to B and back. The pulse takes 2 min and 30s to complete its entire journey. The speed of the pulse moving on the rope is

A man generates a symmetrical pulse in a string by moving his hand up and down. At t = 0, the point in his hand moves upward passing through mean position. The pulse travels with speed of 3 m/s on the string & his hands passes 6 times in each second from the mean position. Then the point on the string at a distance 3 m will reach its upper extreme first time at time :- 1.25 sec. 1 sec  sec.none

A bob of mass m is tied with a light rope and is oscillating about the mean position M. If A and B are the extreme positions, then Horizontal acceleration of the bob at A is

A string of mass 2.50 kg is under a tension of 200 N. The length of the stretched string is 20.0 m. If the transverse jerk is struck at one end of the string, how long does he disturbance take to reach the other end ?

A body starting from rest accelerates uniformly by along a straight line at the rate of 10 m/s2 for 5s. It moves for 2s with uniform velocity of 50 m/s. Then it retards uniformly and comes to rest in 3s. The total distance travelled by the body is:A 200 m B 300 m C 400 m D 600 m

Two people, one twice as massive as the other, attempt a tug-of-war with 12 meters of rope on frictionless ice. After a brief time, they meet. The heavier person slides a distance of Group of answer choices4 m.0 m.6 m3 m
