Projectile Motion Practice Problems
1. A marble is held at rest 1.5 m above the floor.
a. Determine how long it will take the marble to hit the floor.
b. Determine how fast the marble will be traveling when it
reaches the floor.
2. A cannon is shot with a horizontal velocity of 8m/s. After t=5s:
a. How far, horizontally, is the cannon ball from the cannon?
b. How far, vertically, has the cannon ball fallen?
c. Calculate the vertical velocity of the cannon ball after 5s.
d. Calculate the horizontal velocity of the cannon ball after 5s.
3. An apple is dropped out the window of your car as your moving
25m/s. It takes 0.4 seconds to hit the ground.
a. How far did the apple travel horizontally?
b. How far did the apple travel vertically?
c. Calculate the vertical velocity of the apple after 0.4s.
d. Calculate the horizontal velocity of the apple after 0.4s.
4. A Physics book is given a shove and leaves the top of a desk. The
book left the desk horizontally with a velocity of 1.25 m/s and hit
the ground 4.00 s later.
a. Find how high the top of the desk is above the ground.
b. Find how far horizontally the projectile traveled before
hitting the ground.
c. Calculate the vertical component of the final velocity the
moment before the book hit the ground.
d. Find the final velocity of the projectile the instant before
it hit the ground.

5. A plane is flying horizontally above the ground. It is to drop a
package on to the ground below and hit a specific spot. If the
plane is traveling at 56.4 m/s and has an altitude of 123 m above
the target, how far horizontally from the target will the plane
need to drop the package?
6. A fireman is running to the rescue of Lamby. Lamby jumps from
the top edge of 20.0 m tall burning building. Lamby has a
horizontal velocity of 2.0 m/s when he leaves the edge of the
building. The fireman is 40.0 m from the edge of the building
when Lamby jumps.
a. How fast will the fireman have to run at to catch Lamby at a
height of 1.6m above the ground?
b. How far from the side of the building will they be when Lamby
is saved?
