On an asteroid, a ball takes 11.2 s to fall 27.0 m to the ground. What is the acceleration due to gravity on the asteroid? Acceleration due to gravity
A. 0.4049 m/s^2
B. 0.4526 m/s^2
C. 0.4175 m/s^2
D. 0.4668 m/s^2
E. 0.4305 m/s^2
F. 0.4065 m/s^2

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.

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d
