The angular frequency of a spring block ...

The angular frequency of a spring block system is `omega_(0)`. This system is suspeded from the ceilling of an elevator moving downwards with a constant speed `v_(0)`. The block is at reast realtive to the elevator. Lift is suddenly stopped. Assuming the downward as a positive direction, choose the wrong statement :

A

the amplitude of the block is `(v_(0))/(omega_(0))`

B

the initial phase of the block is `pi`

C

the equation of motion for the block is `(v_(0))/(omega_(0)) sin omega_(0)t`

D

the maximum speed of the block is `v_(0)`

Text Solution

Verified by Experts

The correct Answer is:
B
Maximum speed `v_(0) rArr A = (v_(0))/(omega^(0))`
So equation of motion `x = (v_(0))/(omega_(0)) sin(omega_(0)t)`

Two blocks A and B are joined together with a compressed spring. When the system is released, the two bloks appear to be moving with unequal speeds in the opposite directions as shown in figure. Select incorrect statements(s) :

Two blocks A and B of mass m and 2m respectively are connected by a massless spring of spring constant K . This system lies over a smooth horizontal surface. At t=0 the bolck A has velocity u towards right as shown while the speed of block B is zero, and the length of spring is equal to its natural length at that at that instant. {:(,"Column I",,"Column II"),((A),"The velocity of block A",(P),"can never be zero"),((B),"The velocity of block B",(Q),"may be zero at certain instants of time"),((C),"The kinetic energy of system of two block",(R),"is minimum at maximum compression of spring"),((D),"The potential energy of spring",(S),"is maximum at maximum extension of spring"):}

A frame of reference that is accelerated with respect to an inertial frame of reference is called a non-inertial frame of reference. A coordinate system fixed on a circular disc rotating about a fixed axis with a constant angular velocity omega is an example of non=inertial frame of reference. The relationship between the force vecF_(rot) experienced by a particle of mass m moving on the rotating disc and the force vecF_(in) experienced by the particle in an inertial frame of reference is vecF_(rot)=vecF_(i n)+2m(vecv_(rot)xxvec omega)+m(vec omegaxx vec r)xxvec omega . where vecv_(rot) is the velocity of the particle in the rotating frame of reference and vecr is the position vector of the particle with respect to the centre of the disc. Now consider a smooth slot along a diameter fo a disc of radius R rotating counter-clockwise with a constant angular speed omega about its vertical axis through its center. We assign a coordinate system with the origin at the center of the disc, the x-axis along the slot, the y-axis perpendicular to the slot and the z-axis along the rotation axis (vecomega=omegahatk) . A small block of mass m is gently placed in the slot at vecr(R//2)hati at t=0 and is constrained to move only along the slot. The distance r of the block at time is

Two point masses m_1 and m_2 are connected by a spring of natural length l_0 . The spring is compressed such that the two point masses touch each other and then they are fastened by a string. Then the system is moved with a velocity v_0 along positive x-axis. When the system reached the origin, the string breaks (t=0) . The position of the point mass m_1 is given by x_1=v_0t-A(1-cos omegat) where A and omega are constants. Find the position of the second block as a function of time. Also, find the relation between A and l_0 .
