An object

Sahay Sir > Question Answers > An object
An object , initially at rest , explodes in three fragments. The momentum of two pieces are −3piˆ and −4pjˆ where p is a positive number. The momentum of the third piece (i) will have magnitude 5p (ii) will make an angle tan^−1(4/3) with the x-axis (iii) will make an angle tan^−1(3/4) with the x-axis (iv) will have magnitude 7p

Tags: A bomb explodes in air when it has a horizontal speed of 10m/s. It breaks into two pieces A and B of mass ratio 1:2. If A goes vertically up at a speed of 40m/s , An object , initially at rest , the speed of B is ,
An object, moving with a speed of 6.25 m/s, is decelerated at a rate given by: dt/dv ​= − 2.5v where v is the instantaneous speed. The time taken by the object, to come to rest, would be:
