a stone is thrown straight down from the edge of a roof, 1000 feet above the ground, at a speed of 7 feet per second. a. remembering that the acceleration due to gravity is -32 feet per second squared, how high is the stone 5 seconds later? b. at what time does the stone hit the ground? \ c. what is the velocity of the stone when it hits the ground?

Answer :

A rock thrown straight up has a velocity of around 10 m/s and an acceleration of zero when it reaches the precise top of its route.

What is the rate of acceleration of a rock thrown straight up?

The acceleration on the stone remains constant regardless of the direction or size of the velocity. Gravity on the surface of the Earth has a value of around 9.80 m/s2, hence the name acceleration.

How quickly does a rock fall when it is thrown?

−9.80 m/s2

Throughout the entire journey, both when it is travelling uphill and when it is moving downhill, its acceleration is 9.80 m/s2. It should be noted that the values for represent the locations  displacements.
