A mineral has a mas of 53grams. Its volume is 12millileters. What is the
density?

4.45 g/mL

Explanation:

to get density, you simply divide the volume by the mass, so your equation would look like p= 53/12

P being density, which is what you are solving for! Hope this helps!!

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
