A Range Equation Problem with Two Parts

The video tutorial covers a projectile motion problem where Mr. P throws a ball towards a bucket. The problem involves calculating the correct launch angle using the range equation, given that the ball is initially 34 cm short of the target. The tutorial explains the use of the range equation, solves for the initial speed, and determines the correct launch angle for the second attempt. It concludes with a discussion on complementary angles, which also provide a valid solution.

What is the magnitude of the initial velocity determined for the first throw?

What is the launch angle required for the second attempt to land the ball in the bucket?

Explain the concept of complementary angles in the context of projectile motion.
