    Correct Option - 2


    Detailed Solution:

    Sol. Before collision ⇒

    It undergoes completely inelastic collision

    Using conservation of linear momentum

    Initial momentum = Final momentum

    ⇒ m v 1 = m v 2 + m v 2

    ⇒ m v 1 = 2 m v 2

    ⇒ v 1 v 2 = 2 1

For 2 kg block

T – 2g sin37 = 2a        . (i)

For 4 kg block

4g – 2T =  4 a 2

2g – T = a                    . (ii)

T = (2g – a)

2g – a – 2g ×  3 5  = 2a

3a = 2g ×  2 5

a = 4 g 1 5

In the system shown below, the pulley 4 string are ideal. If the acceleration of blocks is g 8 , find m 1 m 2  

 
A
alok kumar singh

a = ( m 1 − m 2 ) g ( m 1 + m 2 ) = g 8

8m1 – 8m2 = m1 + m2

7m1 = 9m2

m 1 m 2 = 9 7
