A type 3 projectile is one which combine types 1 and 2, the projectile has a change in height (like type 1) and is launched on an angle (like type 2). It still has V fy = 0 at the high point. Easy way: find the final velocity in the y - direction for the projectile After finding V fy , then use it to find the time in the air Find your range using t in the equation: ALTERNATIVE METHOD: A type iii projectile is a quadratic in terms of t Type iii projectiles Wednesday, November 03, 2010 11:04 AM Kinematics & Projectiles Page 1

A type 3 projectile is one which combine types 1 and 2, the projectile has a change in height (like type 1) and is launched on an angle (like type 2). It still has Vfy = 0 at the high point.
Easy way: find the final velocity in the y - direction for the projectile
After finding Vfy, then use it to find the time in the air
Find your range using t in the equation:
ALTERNATIVE METHOD:A type iii projectile is a quadratic in terms of t

The same problem as a quadratic:
Kinematics & Projectiles Page 2
Still use to find range
.
The quadratic formula may be used to find t.

The easy way (really the hard way):Find the final vertical velocity at the height you're asked usingVfy
2 = Voy2 +2aydy
Use this in conjunction with Vfy = Voy +ayt to find t
A cat is kicked at 20 m/s at 30o above horizontal off a 20 m high building, find the time it spends in the air, the range, the final velocity at impact and velocity at the high point.
