State if the motion is transverse, longitudinal or a combination of both. Motion of a kink in a long coil spring produced by displacing one end of the spring sideways.

Given below are some eamples of wave motion. State in each case, if the wave motino is transverse, longitudinal or a combination of both? (i) Motion of a kink in a long coil spring produced by displacing one end of spring side ways. (ii) Waves produed in a cylinder containing a liquid by moving its piston back and forth. (iii) Waves produed by a motor boat sailing in water. (iv) Light waves travelling from sun to earth. (v) ultrasonic waves in air produced by a vibrating quartz crystal.

A body of mass m is attached by an inelastic string to a suspended spring of spring constant k . Both the string and the spring have negligible mass and the string is inextensible and of length L . Initially, the mass m is at rest. Q. If the mass m is now raised up to point A (the top end of the string see fig. and allowed to fall from rest, the maximum extension of the spring in the subsequent motion will be

State in the following cases, whether the motion is one, two or three dimensional motion is one, two or three dimesional motion: (a) a dite fluing onwindy day (b) a speeding car on a long straight high way (c ) a carrom coin rebounding from the side if the board (d) a plane revolving around its star.

A mass m = 50 g is dropped on a vertical spring of spring constant 500 N nfl from a height h= 10 cm as shown in figure (18-E14). The mass sticks to the spring and executes simple harmonic oscillations after that. A concave mirror of focal length 12 cm facing the mass is fixed with its principasl axis coinciding with the lilne of motion of the mss, its pole being at a distance of 30 cm from the free end of the spring. Find the length in which the image of the mass oscillates

Two light spring of force constants k_(1) and k_(2) and a block of mass m are in the line AB on a smooth horizontal table such that one end of each spring is fixed on right supports and the other and is free as shown in figure The distance CD between the free ends of the spring is 60 cm . If the block (k_(1) = 1.8 N//m, k_(2) = 3.2 N//m and m = 200g) . Is the motion simple harmonic?

One side of spring of initial, instreached length l_(0) = 1m , lying on a frictionless table, is fixed, the other one is fastened to a small puck of mass m = 0.1 kg . The puck is given velocity in a direction perpendicular to the spring at an initial speed v_(0) = 11 m//s . In the course of the motion, the maximum elogation of the spring is l = l_(0)//10 . What is the force constant of the spring (in SI units) ? .

A 2144kg freight car roles along rails with negligible friction. The car is brought to rest by a combination of two coiled springs as illustrated in figure. Both springs are described by Hooke's law with k_1=1600Nm^-1 and k_2=3400Nm^-1 . After the first spring compresses a distance of 30.0cm , the second spring acts with the first to increase the force as additional compression occurs as shown in the graph in figure. The car comes to rest 50.0cm after first contracting the two-spring system. Find the car's initial speed (i n xx10^-1Nm^-1) .
