Question

can someome please answer these

What is the total time of flight of the dart from the previous problem? Round to two decimals

If rain droplets could fall in a vacuum, they would fall with an acceleration of 9.8 m/s2 in magnitude. How long would it take for a raindrop to fall in a vacuum if it fell from a height of 500.0 meters? Assume the raindrops start from rest. Round to the nearest whole number.

Answer 1

The time taken for the rain drop to fall through a distance of 500 meter can be calculated using the equation

Here, ,

Since the rain drops are failing from rest

Substituting for s, a, and u we get

​​​​​​

Therefore, the time taken for the rain drop to fall through a distance of 500 meter is approximately 10s.
