The density of a block of wood is 2.7 g/cm and a mass of 583.3 g. What is its volume?
A
0.5 cm
B
21.6 cm
с
216.0 cm
D
1574.9 cm

C. 216.0 cm³

Explanation:

                                          Volume = mass ÷ density

                                          Volume = 583.3 g ÷ 2.7 g/cm

                                          Volume = 216 cm³

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.
