A spring compressed by `0.1`m develops a restoring force 10N. A body of mass 4kg is placed on it. Deduce `(i)` the force constant of the spring `(ii)` the depression of the spring under the weight of the body `(` take `g=10N//kg)` and `(iii)` the period of oscillation, if the body is left free.

A spring compressed by 0.2 m develops a restoring force of 25 N. A body of mass 5 kg is placed over it. Deduce (i) force constant of the spring (ii) the depression of the spring under the weight of the body and (iii) the period of oscillation, if the body is disturbed. Take g=10 N kg^(-1) .

On compressing a spring by 0.5 m, a restoring force of 20 N is developed. When a body of mass 5 kg is placed on the spring, then calculate the (a) force constant of the spring. (b) the distance through which the spring is depressed under the weight of the body. (c ) the period of oscillation of the spring if the the body is pushed down and then released.

When a spring is compressed by 0.05 m a restoring force of 10 N is developed in it. Then the force constant of the spring is

A spring is compressed by 10 cm by a ball of mass 20 g . What will be the potential energy of a spring if the force constant of the spring is 20 N cm^(-1) .

Figure shows a force compression curve of a spring. A body of mass 5kg moving with the velocity of 8m//s hits the spring. Calculate the force constant of the spring and also the compression produced in the spring when the body hits it.

If a body of mass 0.98 kg is made to oscillate on a spring of force constant 4.84 N/m the angular frequency of the body is

A body of mass 16 kg is made to oscillate on a spring of force constant 100 N kg^(-1) . Deduce the angular frequency.

A body of mass 1 kg oscillates on a spring of force constant 16 N/m. Calculate the angular frequency.

On a smooth inclined plane a body of mass M is attached between two springs. The other ends of the springs are fixed to firm supports. If each spring has a force constant k, the period of oscilation of the body is (assuming the spring as massless)
