SUMMARY
The discussion focuses on calculating the trajectory of a ball rolling off a stairway with a horizontal velocity of 1.50 m/s. The stairs are 20 cm high and 20 cm wide. Using the equations of motion, specifically d = v1t + at^2 and the time of flight t = 2viSinθ/ 9.8, participants concluded that the ball will hit the step where the horizontal displacement x equals the vertical height h. The key is to equate the expressions for x and h to determine the exact step impacted.
