A string of length 40 cm and weighing 10 g is attached to a spring at one end and to a fixed wall at the other end. The spring has a spring constant of `160 N m^-1` and is stretched by 1-0 cm. If a wave pulse is produced on the string near the wall, how much time will it take to reach the spring ?

A wire of length 50 cm and weighing 10 gm is attached to a spring at one end and to a fixed wall at the other end. The spring has a spring constant of 50 N/m and is stretched by 1 cm. If a wave pulse is produced on the string near the wall, then how much time will it take to reach the spring?

A string of length 10.0 m and mass 1.25kg stretched with a tension of 50N. If a transverse pulse is created at one end of the string, how long does it take to reach the other end ?

A spring of spring constant 5 xx 10^(3) N//m is stretched initially by 5 cm from the unstretched position. The work required to further stretch the spring by another 5 cm is .

A spring of spring constant 5 xx 10^(3) N//m is stretched initially by 5 cm from the upstretched position. The work required to further stretch the spring by another 5 cm is .

There are two identical springs, each of spring constant 240 N/m, one of them is compressed by 10cm and the other is stretched by 10 cm. What is the difference in the potential energies stored in the two springs ?

If a mass of 2.0 kg is attached to one end of a spring and the spring has a spring constant 1500Nm^(-1) , then calculate the maximum velocity and acceleration of the mass body for an amplitude 0.05 m .

A spring has spring constant k = 200 N//m . How much work does it take to stetch the spring 10 cm from equilibrium ?

One end of a spring of force constant k_1 is attached to the ceiling of an elevator. A block of mass 1.5kg is attached to the other end. Another spring of force constant k_2 is attached to the bottom of the mass and to the floor of the elevator as shown in figure. At equilibrium, the deformation in both the spring is equal and is 40cm . If the elevator moves with constant acceleration upward, the additional deformation in both the spring is 8cm . Find the elevator's accelerationn ( g=10ms^-2 ).
