To determine the speed of a ball thrown straight up at 20 m/s when caught, it's essential to apply the principles of projectile motion. The discussion highlights confusion over whether to calculate speed or distance, with emphasis on the need for relevant equations. The original poster acknowledges a typographical error in their question but is urged to consider applicable physics equations for a complete analysis. The conversation underscores the importance of understanding motion dynamics in solving such problems. Proper application of equations will yield the correct speed upon catching the ball.
