Two objects have the same momentum. Which of the following is true?
I. The masses of the objects are equal
II. The speeds of the objects are equal
III. The velocities of the objects are equal
IV. The direction of motion of each object is the same.
a)II and III
b) Ⅳonly
c) II only
d) I and II
e) I only
f) II and IV
g) III only

Answer :

Answer:

(IV) The direction of motion of each object is the same.      

Explanation:

The momentum of an object is given by :

p = m v

m is the mass of an object

v is the velocity of an object

It is given that two objects have the same momentum such that,

[tex]p_1=p_2[/tex]

[tex]m_1v_1=m_2v_2[/tex]

From above equation,

Mass, speed and velocity of both objects must not same but the direction of motion of each object is the same. Hence, the correct option is (b).
