A rectangle solid box of length `0.3m` is held horizontally , with one of its sides on the edge of a platform of height `5m` . When released , it slip off the table in a very short time `T=0.01` s, remaining essentially horizontal . The angle by which it would rotate when it hits the ground will be `("in radian")` close to:

A ball is rolled oof along the edge of table (horizontal) with velocity 4 m/s . IT hits the ground after time 0.4 s. Which one of the following is wrong ?

A uniform chain of mass m and length l is on a smooth horizontal table with (1/n)^th part of its leght is hanging from one end of the table. The velocity of the chain, when it completely slips off the table is

A ball is rolled off along the edge of a horizontal table with velocity 4m//s . It hits the ground after time 0.4s . Which of the following are correct?

A ball is rolled off along the edge of the table (horizontal ) with velocity 4 ms^(-1) .It hits the ground after time 0.4 s. Which one of the following statements are wrong ? ( g= 10 ms^(-2)).

A ball is rolled off along the edge of the table (horizontal ) with velocity 4 ms^(-1) .If hits the ground after time 0.4 s. Which one of the following statements is wrong ? ( g= 10 ms^(-2)).

The childern are trying to shoot a marble into a marble into a small box using a spring loaded gun that fixed on a table and shoots horizontally from the edge of the table. The centre of the box is a horizontal distance 5m from the edge of the table. The first child compresses the spring a distance 2cm and finds that the marble falls short of its target by a horizontal distance 3m . By what distance x should the second child compress the spring to score a direct hit on the box?

A rectangular rigid fixed block has a long horizontal edge. A solid homogeneous cylinder of radus R is placed horizontally at rest its length parallel to the edge such that the exis of the cylinder and the endg of the block are in the same vertical plane as shown in the figure below. Ther is sufficinet friction present at the edge s that a very small displacement causes the cylinder to roll off the edge without slipping. Determine: (a) the angle theta_c through which the cylinder rotates before it leaves contact with the edge, (b) the speed of the centre of mass of the cylinder before leaving contact with the edge, and (c) the ratio of the translational to rotational kinetic energy of the cylinder when its centre of mass is in horizontal line with the edge.
