Max RANGE of a projectile thrown from the top of a ramp.

Click For Summary
SUMMARY

The discussion centers on determining the optimal angle \(\theta\) for maximizing the range \(R\) of a projectile launched from the top of a ramp inclined at an angle \(\phi\) to the horizontal. Participants noted the complexity of the equations involved and suggested the use of trigonometric identities to simplify calculations. The conversation highlights the need for a clear understanding of projectile motion principles and the impact of ramp angles on trajectory.

Homework Statement



A projectile is thrown from the top of the ramp. Find the angle [itex]\theta[/itex] of the throw that gives a max range R down the ramp. [itex]\phi[/itex] is the angle made from the base of the ramp to the x-axis.

2. The attempt at a solution

Tried a number of times but failed to get anything that seemed moderately appropriate, i.e. getting long equations that are obviously too complex to be the answer.

Appreciate the help.

Thanks.
