A group of students performed the same "Conservation of Mechanical Energy" experiment that you performed in lab. However, instead of keeping the horizontal portion of the ramp at a constant height h2 from the tabletop, they varied this height and released the ball from the same height h1 each time. They then entered their results into the first two columns of the table shown in part (a).
(a) Complete the table below.
Completed table successfully, Avg V2 about 264 cm
(b) Use the average value of v2kin to determine the height h1 through which the ball falls.
You said: "Avg V2 about 264 cm". What is V2 ? – presumably a distance, as it is measred in cm – but what distance?????
You haven’t fully explained the question so it’s hard to understand. That’s probably why you have no answers.
