Projectiles. Physics 2010. Projectile Motion. Free-fall with an initial horizontal velocity (assuming we ignore any effects of air resistance) The curved path that an object follows when thrown or launched near the surface of Earth is called a trajectory. Projectiles.
(assuming we ignore any effects of air resistance)
a. Determine how much time it takes to fall.
b. Determine how far from the base of the cliff it is when it hits the ground.
c. Determine how fast it is moving vertically when it hits the ground.
d. Determine what its total velocity is when it hits the ground.
The launch velocity of the projectile needs to be split up into its component parts for analysis purposes.
Note: the initial vertical velocity is no longer zero!!!
Initial velocity analysis:
Vyi = V sinθ
Vx = Vcosθ
These values can now be used in the kinematic equations…
a. How high will it go?
b. How much time does it spend in the air?
c. How far away from you will it hit the ground?
d. What is the ball’s velocity when it hits the ground?
a. Find the range of the ball.
b. Find the maximum height of the ball.
a. Find its “hang time” (time that the ball is in the air).
b. Find the distance the ball travels before it hits the ground.
c. Find its maximum height.
