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.
| Trial # | Height of ramp from table top h2 (cm) | Horizontal distance d (cm) | v2kin (cm/s) |
|---|---|---|---|
| 1 | 9.82 | 31.71 | |
| 2 | 21.31 | 46.77 | |
| 3 | 30.99 | 55.79 | |
| 4 | 43.77 | 65.73 | |
| 5 | 49.76 | 69.89 |
(b) Use the average value of v2kin to determine
the height h1 through which the ball falls.

A group of students perform the same "Conservation of Mechanical Energy" experiment that you performed in lab by allowing a solid sphere and then a solid cylinder to roll down the ramp. The solid sphere was released from a height of 12.9 cm. From what height hcylinder should the solid cylinder be released so that it has the same speed as the solid sphere when it reaches the bottom of the ramp?
