Q
What are the assumptions in projectiles?
A
- no air resistance
- acceleration due to gravity acts downwards as a constant
- working in two dimensions
- object is a particle
- there is a flat horizontal ground/plane

Q
What equation do you use for the x plane in projectiles?
A
S=VT
4
Q
How do you resolve initial velocity?
A
Find the initial velocity in the x and y direction
x = FcosO
y = FsinO
