Mixed Two-Dimensional Projectiles
This worksheet allows you to practice three different modes of releasing two-dimensional projectiles.
release A has s
release B has s
release C has s
release D is thrown horizontally and has s
For each of the following questions:
the release velocity V =
when thrown at an angle (projectiles A, B, and C), the angle is
the height of the cliff (projectiles C and D) is
the barrier projectile B strikes is
What is the height of the apex for projectile A?
How fast is projectile A moving as it passes through its apex?
What is the magnitude of projectile A's resultant impact velocity when it returns to the ground?
How much time does projectile B spend in the air before it strikes the barrier?
At what angle does projectile B strike the barrier?
How far horizontally from the point of release is the barrier located?
How high is the apex of projectile C above the bottom of the cliff?
As projectile C passes through its apex which of the following statenments is true?
its instantaneous velocity equals zero, and its acceleration equals 0 //sec
its instantaneous velocity equals 20.0 m/sec and its acceleration is -9.8 m/sec
its instantaneous velocity equals 17.5 m/sec and its acceleration is -9.8 m/sec
its instantaneous velocity equals 19.7 m/sec and its acceleration is +9.8 m/sec
What is the magnitude of projectile C's resultant impact velocity when it returns to the ground?
How much time does projectile C spend in the air before it strikes the ground at the base of the cliff?
How much time does projectile D spend in the air before it strikes the ground at the base of the cliff?
At what angle does projectile D strike the ground at the base of the cliff?
How far from the base of the cliff does projectile D strike the ground?
