A 2 kg block rests over a small hole in a table. A woman beneath the table shoots a 15 gm bullet through the hole into the block, where it lodges. How fast was the bullet going if the block rises 75 cm above the table ?

A block of mass M is situation on a smooth horizontal frictionless table. A thread tied to the block passes through a hole in the table and carries a mass m at its other end if the length of the thread above the table is l, what should be the value of m so that it may remain suspended at a constant height and the block M moves in a circular p-ath with an angular velocity omega on the table?

A 10 gm bullet is fired from a rifle horizontally into a 5 kg block of wood suspended by a string and the bullet gets embedded in the block. The impact causes the block to swing to a height of 2.5 cm above its initial level. The velocity of the bullet is

A 2 kg block of wood rests on a long table top. A 5 g bullet moving horizontally with a speed of 150 ms^(-1) is shot into the block and sticks to it. The block then slides 2.7m along the table top and comes to a stop. The force of friction between the block and the table is

A block of a mass of 10 kg rests on a horizontal table. The coefficient of friction between the block and the table is 0.05. When hit by a bullet of mass 50 g moving with speed v, that gets embedded in it, the block moves and comes to rest after moving a distance of 2 m on the table. If a freely falling object were to acquire speed 10v​ after being dropped from height H, then neglecting energy losses and taking g=10 S.I. , the value of H is close to:

A 4 kg block is on a smooth horizontal table. The block is connected to a second block of mass 1 kg by a massless flexible taut cord that passes over a frictionless pulley. The 1 kg block is 1m above the floor. The two block are released from rest. With what speed does the 1 kg block hit the ground? .
