A 10 kg metal block is attached to a spring of spring constant 1000 N `m^(-1)`. A block is displaced from equilibrium position by 10 cm and released. The maximum acceleration of the block is

A

10 `ms^(-2)`

B

100`ms^(-2)`

C

200`ms^(-2)`

D

0.1 `ms^(-2)`

Text Solution

Verified by Experts

The correct Answer is:
a
`k=1000 Nm^(-1)`, extention x=10 cm =0.1 m
`:.` Magnitude of restoring force `F=kx=1000xx0.1=100N`
acceleration `a=F/m=(100)/(10)`
`:. a=10 m//s^2`

A 1 kg block situated on a rough incline is connected to a spring of spring constant 100 Nm^(-1) as shown in Fig. 6.17. The block is released from rest with the spring in the unstreched position. The block moves 10 cm down the incline before coming to rest. Find the coefficient of friction between the block and the incline. Assume that the spring has a negligible mass and the pulley is frictionless.

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 .

Two rectangular blocks A and B of masses 2 kg and 3 gk respectively are connected by a spring of spring constant 10.8Nm^(-1) and are placed on a frictionless horizontal surface. The block A was given an initial velocity of 0.15 ms^(-1) in the direction shown in the figure. The maximum compression of the spring during the motion is
