A table with smooth horizontal surface is turning at an angular speed `omega` about its axis. A groove is made on the surface along a radius and a particle is gently placed inside the groove at a distance a from the centre. Find the speed of the speed of the particle as its distance from teh centre becomes L.

A table with smooth horiztonal surface is truning at an angular speed omega abouyt its axis. A groove is made on the surface along a radius and a particle is gently placed inside the groove at a distance a from the centre. Find the speed of the speed of the particle as its distance from teh centre becomes L.
A very small groove is made in the earth, and a particle of mass m_(0) is placed at (R)/(2) distance from the centre. Find the escape speed of the particle fro that place.
a narrow tunnel is dug along the diameter of the earth, and a particle of mass m_(0) is placed at R/2 distance from the centre. Find the escape speed of the particle from that place.
Earth and moon centre distance is 'r'. From the mid point what should be the speed of the particle so that it can escape to infinity?
A table with smooth horizontal surface is fixed in a cabin that rotates with a uniform angular velocity omega in a circular pathof radius R. A smooth groove AB of length L(ltltR) is made on the surface of the table. The groove makes an angle theta with the radius OA of the circle in which the cabin rotates. A small particle is kept at the point A in the groove and is released to move along AB. Find the time taken by tehparticle to reach the point B.
A particle moving on the inside of a smooth sphere of radius r describing a horizontal circle at a distance r//2 below the centre of the sphere. What is its speed ?
The speed v of a particle moving along a straight line is given by a+bv^(2)=x^(2) , where x is its distance from the origin. The acceleration of the particle is
A particle is released from height S from the surface of the earth. At a certain height its KE is three times its PE. The height from the surface of earth and the speed of the particle at that instant are resp.
A uniform rod of mass m and length L lies radialy on a disc rotating with angular speed omega in a horizontal plane about vertical axis passing thorugh centre of disc. The rod does not slip on the disc and the centre of the rod is at a distance 2L from the centre of the disc. them the kinetic energy of the rod is
