Answer 1

GIVEN :

A body of mass M moving at a constant velocity V hits another body of the same mass moving with a velocity V by 2 But in opposite direction in sticks to it

TO FIND :

The common velocity after collision .

SOLUTION :

◆VELOCITY of mass m" +m' is found by equation ,

◆m'u' + m"u" = 2mv'

◆Where m' ,m" are first and second masses respectively.

v' - final velocity.

u ' ,u" are first and second velocities respectively.

◆Here,

◆m' + m" = 2m ; as m' = m" =m

◆u ' = v ,

◆u" = -v/2 (-ve sign since particle is in opposite direction.)

◆Substituting values,

mv + -(mv/2) = 2mv'

mv/2 = 2mv'

v' = v/4.

ANSWER :

Final velocity, v' = v/4.

Answer 2

Answer:

In this question we have to do firstly we will multiply it and then we will divided by we buy do and then velocity will be3and what will be the answer it was shown no whwre
