8.
Two balls that look exactly the same but have different masses are dropped at the same time from the top of the ladder. Which ball will hit the ground first?
a)
The ball with more mass will hit the ground first.
b)
The ball with less mass will hit the ground first.
c)
Both balls will hit the ground at the same time.

9.
Which equation would you use to find the acceleration of an automobile whose speed decreases from 48 m/s to 4 m/s in 11 seconds?
HINT: Look at the answers, only one makes sense...
HINT: Look at the answers, only one makes sense...
a)
(48 m/s – 4 m/s) / 11 s = 4 m/s2
b)
(48 m/s + 4 m/s ) / 11 s = 4.7 m/s2
c)
(4 m/s – 48 m/s) = - 44 m/s
d)
(4 m/s – 48 m/s) / 11 s = - 4 m/s2
