Problem 2: Eight objects are launched horizontally from the top of a building. Some objects have mass m, the
others have mass 2m. Some objects are launched with initial speed v, others with initial speed 2v. Some objects.
are launched from the middle of the building so that they have initial height H, the others are launched from the
top of the building with initial height 2H.

(a) Rank the objects based on the time that elapses while they are a projectile from longest to shortest amount
of time. (If any objects have the same projectile time, put an equal sign between those letters.)
Object D
2m
(b) Rank the objects based on the horizontal distance they travel before landing from farthest to shortest.
Least Projectile Time
2v
Shortest Horizontal Distance
(c) Rank the objects based on the acceleration (magnitude) each object has while it is a projectile.
Highest Magnitude Acceleration
Lowest Magnitude Acceleration
Briefly explain how you determined your ranking.
(d) Rank the objects based on the net force (magnitude) each object has while it is a projectile.
Highest Magnitude Net Force
Briefly explain how you determined your ranking.
