Question

A glass falls from a table top and smashes on the floor 0.6 seconds later. How high is the table?

Equations that can be used
Vv=gt, dv=1/2gt^2, t=2d/g.

Answer 1

1.8 m

Step-by-step 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 height 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.

Data

• t = 0.6s

• g = 9.81 m/s²

• d = ?

Equation

• d =
  `(1)/(2)`
  `gt`²

Math & Units

• d = 4.905 (0.6²)
• d = 442.676

Hence the table is 1.8 m high
