# How to get R= 2 ( square root ) h1h2

• I
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)

You may want to post this in the Homework Forum. Do you know about energy and kinematic equations?

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 PeroK
