Question

question 1-5
hail is a frozen form of precipitation that occurs during severe thunderstorms and can cause significant damage to property, crops, and life. severe hail is considered to be baseball - sized or larger, averaging 0.200 kg in mass. calculate the potential energy of baseball - sized hail prior to falling as precipitation given that the average height at which hail forms is 8352 m above earth’s surface.
options:
16,387,000 j
1,670,000 j
16,387 j
1670 j

Explanation:

Step1: Recall gravitational PE formula

Gravitational potential energy is $PE = mgh$, where $m$ = mass, $g = 9.8\ \text{m/s}^2$ (gravitational acceleration), $h$ = height.

Step2: Substitute given values

$m = 0.200\ \text{kg}$, $h = 8352\ \text{m}$
$PE = 0.200 \times 9.8 \times 8352$

Step3: Calculate the product

First compute $0.200 \times 9.8 = 1.96$, then $1.96 \times 8352 = 16369.92 \approx 16387$

Answer:

16,387 J
