Impulse = change in momentum = F x dt
Where F is sufficiently large and dt is very small(tending to zero).

Therefore impulse = mass x final velocity - mass x initial velocity
                                = 975 x 3 - 975 x 0.5
                                = 2437.5 Kg-m/s. 
Hence option C is correct.

You make the following measurements of an object 42kg and 22m3 what would the objects density be
miv72 [106K]
The density of the object is approximately 1.91 kg per m³.

42 kg is a measure of mass, and 22 m³ is a measure of volume. Knowing this, you can use the relationship $$density = mass / volume$$ to solve for the object's density.

42 kg \div 22 m³ \approx 1.91 kg per m³.
