**Very Hard Projectile Motion making me nuts<Help, Urgent!>**

Hey there, i am in grade 12 4u physics course and i would really appreciate it if someone can help me out with the following Projectile Motion questions. I tried to figure out how to do it but i can't think of any.

**Question:1 Title:"Hit the floor Target"**

Diagram:

Given:

Δdx=4.950 m

Δdy=-1.130m

Vi=6.52 m/s

Solve for Θ (theta).

**Question:2 Title: "Colliding Projectiles"**

2 projectiles, one purely horizontal, situated above the other- angular are set to collide in mid-air

Given:

Vix=4.80 m/s

2.0m (separation at launch vertically)

Solve for Θ (theta) ; x- separation at launch. <full solution format>

Provide: A "flight - path' diagram showing coordinates of collision and Δt for collision.

**Question 3: Title: "Hit the falling Target"**

Diagram:

Given:

Vi=6.52 m/s

Δdx=2.2 m

Δdy=1.650 m

Solve for Θ (theta) <full solution format>
