Initial Velocity Given Distance, Angle, and Initial Height

[Mr.Serious]

Homework Statement

Given your assigned projectile launcher determine the muzzle velocity.

angle of launcher = 45degrees
distance to bottom of barrel = 25.6 cm
distance traveled when fired = 119.2cm

Ignore Air resistance

Homework Equations

I don't know where to start since I have an angle.

The Attempt at a Solution

I don't know where to begin since the projectile is basically starting from a platform at an angle.

 

[Unto]

Start with the Kinematic equations of motion.

Since the cannon ball is fired at an angle, it should have 2 sets of equation (vertical and horizontal).

That should set you off. If you need help, reply back here and I will give you the equations with an explanation.
