Answer:
1.8 m
Explanation:
Given: Glass falls from a table, smashes 0.6 seconds later
To find: How high a table is
Formula: Vv=gt, dv=1/2gt^2, t=2d/g
Solution: A table's <em>height</em> is measured from the top of the edge down to the floor. The tables are shown both have a height of 30 inches, which is common for many tables.

- d = 4.905 (0.6²)
- d = 442.676
Hence the table is 1.8 m high
The average rate at which the cable does work is 294,000 J/s.
The given parameters:
- <em>mass, m = 3000 kg</em>
- <em>height, h = 200 m</em>
- <em>time of motion, t = 20 s</em>
The average rate at which the cable does work is calculated as follows;

Thus, the average rate at which the cable does work is 294,000 J/s.
