Question 1
An object is dropped from 10 ft above the surface of the moon. How long will it take the object to hit the surface of the moon if

◦ 3.85 sec
◦ 1.39 sec
◦ 1.96 sec
◦ 0.96 sec
Question 2
Find the standard equation for the position s of a body moving with a constant acceleration a along a coordinate line. The following properties are known:
i.

= a,
ii.

= v
0 when t = 0, and
iii. s = s
0 when t = 0,
where t is time, s
0 is the initial position, and v
0 is the initial velocity.
◦ s = at
