Question

Use the exact values you enter to make later calculations.

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.

(b) Use the average value of v2kin to determine the height h1 through which the ball falls.

I'm just unsure of what formula to use to find V2Kin

Trial # Height of ramp from table top h2 (cm) Horizontal distanced (cm) v2kin (cm/s) 1 10.03 32.46 2 22.30 47.91 3 30.57 55.92 4 42.42 67.70 5 50.06 71.28

Explanation / Answer

Use the average value of v2kin to determine the height h1 through which the ball falls.

sqrt(981)/((2)(10.03))=6.993088

then multiply this by your d

6.993088*32.46=226.9956

let me know in case of problem.
