PROJECTILE MOTION
It is a special case of two dimensional motion: A particle
moves in a vertical plane with some initial velocity
but its
acceleration is always the free-fall acceleration g, which is
downward.
In projectile motion, the horizontal motion and
the vertical motion are independent from each
other and neither affect the other.
Thus, we can break up the problem into two separate and
easy one-dimensional problems
Analysis of Projectile Motion
The Horizontal Motion
The Vertical Motion
Driving of a cliff. A movie stunt driver on
a motorcycle speeds horizontally of a
50.0m high cliff. How fast must the
motorcycle leave the cliff-top if it is to land
on level ground below, 90.0m from the
base of the cliff?
A punt. Suppose the football in the
figure was a punt and left the punters
foot at a height of 1.00m above the
ground. How far did the football travel
before hitting the ground?
