I eat dicks and and I also masturbate
Given
m1(mass of the first object): 55 Kg
m2 (mass of the second object): 55 Kg
v1 (velocity of the first object): 4.5 m/s
v2 (velocity of the second object): ?
m3(mass of the object dropped): 2.5 Kg
The law of conservation of momentum states that when two bodies collide with each other, the momentum of the two bodies before the collision is equal to the momentum after the collision. This can be mathemetaically represented as below:
Pa= Pb
Where Pa is the momentum before collision and Pb is the momentum after collision.
Now applying this law for the above problem we get
Momentum before collision= momentum after collision.
Momentum before collision = (m1+m2) x v1 =(55+5)x 4.5 = 270 Kgm/s
Momentum after collision = (m1+m2+m3) x v2 =(55+5+2.5) x v2
Now we know that Momentum before collision= momentum after collision.
Hence we get
270 = 62.5 v2
v2 = 4.32 m/s

Answer: Yes
Explanation: A molecule has a bond dipole but not have a molecular dipole.
Dipole moment: dipole moment is the product of the distribution of the charge of the molecules and the distance between of the molecules.
Example:
lets take an example of 
molecule in which two electro negative oxygen atoms are attached with Carbon atom. Oxygen being electro negative will attract the shared pair electrons towards itself and partial negative charge will create on oxygen atom and partial positive charge on carbon atom C.
due to formation of partial positive and partial negative charges dipole moment is created between oxygen and Carbon bond on both the sides in opposite direction.
Since, the dipole moment acting in opposite direction the net dipole moment in the molecule is zero.
Hence, Yes, a molecule has bond dipoles but not have a molecular dipole.
