 Practice Problems Mixed Two-Dimensional Projectiles

Directions: This worksheet allows you to practice three different modes of releasing two-dimensional projectiles. release A has sy = 0
release B has sy > 0
release C has sy < 0
release D is thrown horizontally and has sy < 0 omit
Question 1  For each of the following questions:
• the release velocity V = 21 m/sec
• when thrown at an angle (projectiles A, B, and C), the angle is 26º
• 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? omit
Question 2  How fast is projectile A moving as it passes through its apex? omit
Question 3  What is the magnitude of projectile A's resultant impact velocity when it returns to the ground? omit
Question 4  How much time does projectile B spend in the air before it strikes the barrier? omit
Question 5  At what angle does projectile B strike the barrier? omit
Question 6  How far horizontally from the point of release is the barrier located? omit
Question 7  How high is the apex of projectile C above the bottom of the cliff? omit
Question 8  As projectile C passes through its apex which of the following statenments is true? omit
Question 9  What is the magnitude of projectile C's resultant impact velocity when it returns to the ground? omit
Question 10  How much time does projectile C spend in the air before it strikes the ground at the base of the cliff? omit
Question 11  How much time does projectile D spend in the air before it strikes the ground at the base of the cliff? omit
Question 12  At what angle does projectile D strike the ground at the base of the cliff? omit
Question 13  How far from the base of the cliff does projectile D strike the ground?
