Projectile Motion Practice Problems
1. A cannon is shot with a horizontal velocity of 8m/s.
At t=5s.
a. How far, horizontally, is the cannon ball from the cannon?
b. How far, vertically, has the cannon ball fallen?
2. 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 it travel horizontally?
b. How far did it travel vertically?
3. The Cannon fires a projectile that has a mass of 200 kg. The cannon
produces an acceleration of 300 m/s/s over the length of the barrel
which is 12 m long. The barrel of the cannon is elevated at 230 to the
horizontal.
a. Find the final velocity of the projectile when it leaves the barrel.
b. Find the height above the barrel the projectile will reach at the
highest point.
c. Find the distance the projectile will travel when it returns to the
same height above the ground it started at.
4. 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?

5. A man stands on the top of a building that is 30.0 m tall and throws
a rock with an initial velocity of 40.0 m/s @300.
a. Calculate the maximum height above the roof.
b. Determine how long before the projectile will hit the ground.
c. Determine how far horizontally the projectile will travel before
hitting the ground.
d. Determine the final velocity of the projectile the instant before it
impacts the ground.
6. 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. Find the final velocity of the projectile the instant before it hit the
ground.
7. A snowball rolls off a barn roof that is sloped downward at40.00
below the horizontal. The snowball has a speed of 7.00 m/s as it leaves
the edge of the roof. The roof is 14.0 m above the ground.
a. How long does it take the snowball to reach the ground?
b. A man 1.9 m tall is standing 4.0m from the edge of the roof. Will
the snowball hit him or is he safe?

8. A fireman is running to the rescue of Lamby. Lamby jumps from the
top edge of 20.0 m tall burning building with a horizontal velocity of
2.0 m/s. 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?
