A projectile is launched in the air for 3 seconds and has a horizontal velocity

Option (a) is the correct answer.

Explanation:

Momentum is defined as the ability or tendency of an object to continue moving.

Also, momentum is the product of mass and velocity. It can be shown as follows.

                      p = m × v

where,     p = momentum

               m = mass

               v = velocity

Thus, we can conclude that out of the given options, the formula p = mv show the relationship between momentum, mass, and velocity.
