Question

A watermelon is dropped from the top of a building and falls for 185 seconds. What is the height of the building?

a) 16.8m c) 9.10 m
b) 18.6m d) 168m O​

Answer 1

The height from which the watermelon was dropped, assuming the time of fall is 1.85 seconds, is calculated using the free fall formula h = ½gt². This yields a height of 16.8 meters.

Step-by-step explanation:

To calculate the height from which the watermelon was dropped, we can use the formula for the distance traveled during free fall: h = ½gt², where h is the height, g is the acceleration due to gravity (which is approximately 9.8 m/s²), and t is the time the object is in free fall. Plugging in the given time of 185 seconds (which seems to be a typographical error and should have probably been 1.85 seconds), we can calculate the height.

Calculation using the correct time:

Assuming t = 1.85 seconds:

h = ½(9.8 m/s²)(1.85 s)²

h = 16.8 meters

Therefore, the correct height from which the watermelon was dropped is 16.8 meters, assuming 1.85 seconds as the correct fall time.
