Density is equal to the mass divided by the voulme.
So: 2.5 multiplied by 2.5 by 2.5.
Then: 295 divided by 16.625=18.88g/cm to the power 3

A chunk of ice breaks off a glacier and falls 30.0 m before it hits the water. Assuming it falls freely (there is no air resista
lina2011 [118]

Answer:

The ice chunk will take 2.47 seconds to hit the water.

Explanation:

Height from which ice chunk fell = h = 30.0 m

Initial velocity of the ice chunk = u = 0 m/s

Time taken by ice chunk to cover 30.0 m of height = t

Acceleration due to gravity = g 9.8m/s^2

Using second equation of motion ;

h=ut+\frac{1}{2}gt^2

30.0 m=0 m/s\times t+\frac{1}{2}\times 9.8 m/s^2\times t^2

t=\sqrt{\frac{30.0m/s\times 2}{9.8 m/s^2}}2.47 s

The ice chunk will take 2.47 seconds to hit the water.
