In a vacuum.
rock
The speed of the rock after 5 seconds of free fall would not be 100. The speed of an object in free fall increases by 9.8 m/s every second. After 5 seconds, the speed of the rock would be 49 m/s (approximately), assuming no air resistance.
Somewhere between a rock and a marshmallow...
If you get the speed of the rock then you can use Time= distance/ speed So all you need is the speed and you can work it out
Between rock and paper, paper is lighter. However if dropped from same height they do fall at the same speed.
Yes, a rock can change. It's not as easy to change a rock as it is to change a marshmallow, but it can be done.
The rock would have a speed of 49 m/s after 5 seconds of free fall due to gravity (assuming g = 9.81 m/s^2). This is because its speed increases by 9.81 m/s every second during free fall.
The speed at which the rock will strike the water will be approximately 15.6 m/s. This can be calculated using the formula for free fall with an initial velocity of 0 m/s and height of 25 meters.
The speed of the rock after falling for 5 seconds would be approximately 49 m/s, neglecting air resistance. This speed is the result of the acceleration due to gravity, which is approximately 9.81 m/s^2.
The speed at which a rock falls depends on its weight and shape, as well as the force of gravity acting on it. In general, a rock will accelerate at a rate of about 9.8 m/s^2 due to gravity until it reaches its terminal velocity, which can vary depending on the size and mass of the rock. On Earth, the average speed of a rock falling freely from a significant height is around 53 m/s.
Go through the raspberry forest, hit the giant gorilla on the head and take his marshmallow and the purple rock should be somewhere around there.
A large amount of rock fall is called an avalanche.
