The discussion focuses on deriving the equation for the range (R) of a ball launched horizontally from a ramp, specifically R = 2√(h1h2), where h1 is the height of the ramp and h2 is the height of the table. The scenario assumes no air resistance or friction, and the ball starts with an initial velocity of 0 m/s. Participants emphasize the importance of understanding energy and kinematic equations to solve this problem effectively.
PREREQUISITESStudents studying physics, particularly those focusing on mechanics, as well as educators looking for practical examples of kinematic equations and energy principles.
DLeuPel said:A ball is let down a ramp on top of a table with initial velocity of 0 ms-1. When it reaches the end of the ramp, it is launched horizontally. Knowing that we don’t take air resistance or friction into account, and that the height of the ramp is h1, and that of the table is h2 relative to ground level,how do we get to the equation R (range or distance traveled from the end of the ramp) = 2√(h1h2)
i’m studying the kinematic equations right now and I still haven’t been able to do this exercise. I’ll post right now in the homework section, didn’t know there was one . Thank you PeroKPeroK said:You may want to post this in the Homework Forum. Do you know about energy and kinematic equations?
