A spring with one end attached to a mass...

A spring with one end attached to a mass and the other to a right support is stretched and released

A

Magnitude of acceleration when just releases is maximum

B

Magnitude of acceleration, when at equilibrium position is maximum

C

speed is maximum when mass is a equilibrium position.

D

Magnitude of displacement is always maximum whenever speed is minimum

Text Solution

Verified by Experts

The correct Answer is:
A, C
AT equilibrium position `a=(F)/(m)=(-kx)/(m)`
Hence, when just released `x=x_(max)`
Hence, acceleration is maximum. Thus option (a) is correct.
At equilibrium whole PE will be converted to KE hence KE will be maximum and hence, speed will be maximum.

spring of force constant k clamped rigidly at onoe end and a mass m attached to its free end. A force F applied at the free end stretches the spring. Figure shows the same spring with both ends free and attached to a mass m at either end. Each end of the spring in figure is stretched by the same force F. (a) What is the maximum extension of the spring in the two cases ? (b) If the mass in figure and the two masses in figure are released free, what is the period of oscillation in each case?

A disc of mass m_(2) is placed on a table. A stiff spring is attached to it and is vertical. The other end of the spring is attached to a disc of mass m_(1) What minimum force should be applied to the upper disc to press the spring such that the lower disc is lifted off the table when the external force is suddenly removed?

Two identical springs of spring constant k are attached to a block of mass m and to fixed supports as shown in figure. When the mass is displaced from equilibrium position by a distance x towards right, find the restoring force.

Tow identical springs of spring constant k are attached to a block of mass m and to fixed supports as shown in figure. When the mass is displaced from equilibrum position by a distance x towards right, find the restoring force.

When a 20 N can is hung from the bottom of a vertical spring, it causes the spring to stretch 20 cm. The spring is now placed horizontal on a frictionless table. One end of it is held fixed, and the other end is attached to a 5.0 N can. The can is then moved (stretching the spring) and released from rest. What is the period ("in" xx 10^(-2)s) of the resulting oscillation?

When a mass m is hung on a spring, the spring stretched by 6 cm. If the loaded spring is pulled downward a little and released, then the period of vibration of the system will be

Two identical springs of spring constant k are attached to a block of mass m and to fixed supports as shown in the figure. The time period of oscillation is

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 ?

Figure. (a) shows a spring of force constant k fixed at one end and carrying a mass m at the other end placed on a horizontal frictionless surface. The spring is stretched by a force F. Figure. (b) shows the same spring with both endsf free and a mass m fixed at each free end Each of the spring is streched by the same force F. The mass in case (a) and the masses in case (b) are then released. Which of the following statements are true?

A certain spring stretches 25 cm when a 500 g mass is hung from its end. It is now used as shown in fig. With 2 kg mass at one end placed on a frictionless surface. Suppose the mass is pulled to the right until the spring is stretched to 10 cm and then released. find the speed with which the mass moves through the unstretched position.
