If you have increased the momentum of a moving object without increasing its inertia, then you have . increased the velocity of the object
b. decreased the mass of the objectc. decreased the velocity of the object

Explanation:

The momentum of an object is given by the product of its mass and velocity. It is denoted by p. Mathematically, it is given by :

...........(1)

According to given condition, we have increased the momentum of a moving object without increasing its inertia. Mass of an object is the measure of its inertia.

From equation (1) it is clear that the momentum is directly proportional to the velocity of an object. So, if you have increased the momentum of a moving object without increasing its inertia, then you have increased the velocity of the object.

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
