A glass falls from a table top and smashes on the floor 0.6 seconds later. How high is the table?
1 answer:
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.
<u>Data</u>
- t = 0.6s
- g = 9.81 m/s²
- d = ?
<u>Equation</u>
- d =
²
<u>Math & Units</u>
- d = 4.905 (0.6²)
- d = 442.676
Hence the table is 1.8 m high

Answer:
Option (c).
Explanation:
An object when when projected at an angle, will have some horizontal velocity and vertical velocity such that,
is the angle of projection
The horizontal component of the projectile remains the same because there is no horizontal motion. Vertical component changes at every point.
As a projectile falls, vertical velocity increases in magnitude, horizontal velocity stays the same .
