PhysicsLAB Practice Problems
Mixed Two-Dimensional Projectiles

Directions: This worksheet allows you to practice three different modes of releasing two-dimensional projectiles.

four release modes

release A has sy = 0
release B has sy > 0
release C has sy < 0
release D is thrown horizontally and has sy < 0

Question 1  For each of the following questions:
  • the release velocity V = 23 m/sec
  • when thrown at an angle (projectiles A, B, and C), the angle is 39º
  • the height of the cliff (projectiles C and D) is 16 meters
  • the barrier projectile B strikes is 3.2 meters tall
What is the height of the apex for projectile A?
Question 2  How fast is projectile A moving as it passes through its apex?
Question 3  What is the magnitude of projectile A's resultant impact velocity when it returns to the ground?
Question 4  How much time does projectile B spend in the air before it strikes the barrier?
Question 5  At what angle does projectile B strike the barrier?
Question 6  How far horizontally from the point of release is the barrier located?
Question 7  How high is the apex of projectile C above the bottom of the cliff?
Question 8  As projectile C passes through its apex which of the following statenments is true?
Question 9  What is the magnitude of projectile C's resultant impact velocity when it returns to the ground?
Question 10  How much time does projectile C spend in the air before it strikes the ground at the base of the cliff?
Question 11  How much time does projectile D spend in the air before it strikes the ground at the base of the cliff?
Question 12  At what angle does projectile D strike the ground at the base of the cliff?
Question 13  How far from the base of the cliff does projectile D strike the ground?
