A black ball of mass 2kg moving at velocity of 10 m/sec collides with a stationary white ball of mass 3kg find their common velocity if they stick together after collision?

4 m/s

Explanation:

here

mass of black ball (m1) = 2 kg

initial velocity of black ball (u1) = 10 m/s

mass of white ball (m2) = 3 kg

since white ball is stationary so initial velocity of white ball (u2) = 0 m/s

let v be the common velocity then

by the principle of linear momentum

linear momentum before collision = linear momentum after collision

or, m1u1 + m2u2 = (m1+m2)v [becoz they have common velocity v after collision]

or, v = (m1u1 + m2u2)/m1+m2

or, v = (2*10 + 0)/2+3

or, v = 20/5

~ v = 4 m/s

the answer is most likely c. it shows us that the rules that the pigs make can change on a whim whenever it suits the pigs purpose.

hope this

ok so like i went to wiki and looked up the (constitution x new "hammystan")and it showed me the picture it highlights new hampshire and says first and second session and than it says that they hit up the u.s and was like "ey dude that paper u sent us was adopted it bro thx" xd syays it all on wiki/the pic

i dont really like reading so i guess other people might not like reading either so   imma put the answer in bold italics
