Physics
A steel ball of mass 50 g is rolled from the left toward a ball of lead of mass 500 g. The steel ball is traveling with a velocity of 5 m/s. If no external forces act on either of the interacting bodies, then what will be the direction of the momentum of the steel ball after the head-on collision?

Explanation:
Given that,
The mass of cement, m = 15000 kg
Let us assume that the volume is 10.41 m³
We need to find the density of this cement sample. We know that the density of an object is given by :
We can find the density using above formula,
So, the density of the sample is
.
