Catapult Science • Vt = Velocity (this is what we are looking for) It will be the hypotenuse of this triangle. • Vy = Vertical Velocity (15.7 m/s) • sin = sine – ratio of the height to the hypotenuse. • Θ = theta – symbol to describe how big the angle is in degrees.
• So our formula is: • Vt = Vy /sin Θ Catapult Science • We need to know what the angle is • The distance the projectile travels depends upon the point it leaves the arm. • If the angle of trajectory is Θ to horizontal then the projectile travels 90 – Θ when being thrown.
