JEE Main 10 April 2015 Paper

A block of mass m=10kg 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 υ , that gets embedded in it, the block moves and comes to stop after moving a distance of 2 m on the table. If a freely falling object were to acquire speed

υ

10

after being dropped from height H then neglecting energy losses andtaking g=10ms−2,the value of H is close to :
