Question
A projectile is launchedfrom the ground with a speed v0 directed at angle of q above
the+x-axis. The projectile lands on the ground sometime t after launch. You may need
to look up a few trigidentities to complete this problem.
a. How far does theprojectile travel?
b. Use calculus todetermine the launch angle that will result in the maximumdistance
traveled.
c. Describe what happensif the launch angle is greater than p/2 radians?
d. If I launch aprojectile with an angle q1 isthere an angle q2 that will result inthe
projectile landing in thesame place? Both are launched with the same speedv0. If you
Explanation / Answer
a) The horizontal range of the projectile is R = ( vo coso) * t b) use relation to find launching angleo R = vo2 sin2o /g c) The horizontal range is maximum for a launching angleof 45o d) 1 + 2 =90o d) 1 + 2 =90oRelated Questions
