A pot that falls from a ledge and hits the ground 45 m below hits the ground at
A)30 m/s.
B)60 m/s.
C)120 m/s.
D)more than 120 m/s.

Question

Quizplus · Accepted Answer

The speed of the pot when it hits the ground can be calculated using the formula $v = \sqrt{2gh}$, where $g = 9.8 \, \text{m/s}^2$ is the acceleration due to gravity and $h = 45 \, \text{m}$ is the height. Plugging in the values, $v = \sqrt{2 \times 9.8 \times 45} \approx 29.9 \, \text{m/s}$, which rounds to 30 m/s.
