Initial Velocity Given Distance, Angle, and Initial Height

Click For Summary
SUMMARY

The discussion focuses on calculating the initial muzzle velocity of a projectile launcher given specific parameters: a launch angle of 45 degrees, a barrel height of 25.6 cm, and a distance traveled of 119.2 cm. Participants emphasize the importance of using Kinematic equations of motion, which involve separate calculations for vertical and horizontal components due to the angled launch. The conversation highlights the necessity of ignoring air resistance for accurate calculations.

PREREQUISITES
  • Kinematic equations of motion
  • Understanding of projectile motion
  • Basic trigonometry for angle calculations
  • Concept of vertical and horizontal motion components
NEXT STEPS
  • Study Kinematic equations for projectile motion
  • Learn how to decompose motion into vertical and horizontal components
  • Explore the effects of launch angle on projectile trajectory
  • Investigate the impact of initial height on projectile calculations
USEFUL FOR

Students in physics, educators teaching projectile motion, and anyone involved in engineering or design of projectile systems.

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.

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.
