Projectile Motion
5. A projectile lands 1.8 m from where it was launched at an angle of 65°. What was the
initial launch velocity of the projectile? What was the maximum height obtained by the
projectile?
6. Find the range and height of a projectile that is launched with a velocity of 4.4 m/s at an
angle of 30° and then at an angle of 60º. What are the key similarities and differences
between the 2 shots?
7. A projectile is launched at a rate of 4.4 m/s at an angle of 55°. State the projectiles
position every 0.1 s starting at t=0 s. keep going until the height of the projectile goes
negative. (The shot of Odysseues..)
8. You want to land a projectile 1 m away from where it is launched at 4.4 m/s. What
angles can be used?
9. A projectile is launched at 4.4 m/s at an angle of 30° off a cliff that is 0.95 m tall. Where
will the projectile land?
10. You want to land a projectile that is launched at 4.4 m/s at an angle of 60° in a basket
that is 0.4 m above the ground. How far away from the original launch point should the
basket be placed?
