Answer: See explanation

Explanation:

The density would like be calculated by dividing the mass by volume. This will be:

Density = Mass / Volume

Density = 390 / 50

Density = 7.8g/cm

State: the units for acceleration are?
krok68 [10]

A unit of acceleration needs a unit of length in the numerator
and a squared unit of time in the denominator.

Example:    meters / second²
                    feet / minute²
                    smoots / hour² 
                    furlongs / fortnight² .

Ideally, in order to completely describe an acceleration vector,
you also need to state a direction.

e-lub [12.9K]

Answer:

  the speed of the center of mass stays the same

Explanation:

In a system with no energy loss, momentum is conserved if the mass remains constant. The system described has no change in mass, and energy loss is considered negligible. Hence the product of the total mass and the velocity of its center will be a constant. The center of mass stays the same speed.
