The vertical component of its velocity increases at the rate of 9.8 meters (32.2 feet) per second downward every second. Without involving numbers, simply the vertical component will first be upward at what ever velocity it is when split from the horizontal velocity, then (after reaching the peak of its height at which velocity is zero) it will be a downward vector that, yes, will increase with acceleration due to gravity (which is where the 9.8 meters per second squared came from)
The speed of a dropped stone will be non-uniform. The stone goes faster as it falls by an amount equal to 32 feet per second, per second. That means for each second of falling, the speed increases by another 32 feet per second until terminal velocity is reached.
The stone will return to the ground when its vertical velocity becomes zero and it starts to fall back down. The time it takes for this to happen can be calculated using kinematic equations. In this case, the time can be found by setting the vertical velocity to zero and solving for time.
A stone falls freely from rest The total distance covered by it in the last second of its motion equals the distance covered by it in the first three seconds How long does the stone remain in air?
The acceleration of gravity is 9.8 meters (32.2 ft) per second2.Neglecting air resistance . . .After 8 seconds, the speed is (9.8 x 8) = 78.4 meters per second. (rounded)After 8 seconds, the speed is (32.2 x 8) = 257.6 feet per second. (rounded)

On Earth gravity equals 9.8 m/s^2. If you multiply that by 8 seconds you get: 78.4m/s
Dropping a stone from a tall building is an example of acceleration due to gravity. The stone's speed will increase as it falls until it reaches terminal velocity.
When we tie a stone to a string and whirl it, it moves in a circular path.If the velocity becomes too high then the stone changes to a mass of electrons.It starts radiating energy and ultimately falls in our hand.the energy emitted by the stone is given by E = hv.Where h is Plancks constant and v is the radial velocity of the stone.
H = 1/2 g T2 = (4.9) (64) = 313.6 meters.H = 1/2g T2 = (4.9) x (8)2 = 4.9 x 64 = 313.6 meters
H = 1/2 g T2 = (4.9) (64) = 313.6 meters.H = 1/2g T2 = (4.9) x (8)2 = 4.9 x 64 = 313.6 meters

The approximate gravitational acceleration on Earth is 9.8 meters per second. Neglecting air friction is s equals 4.9 times 16 squared. S is equal to 1254.4 meters which is equal to 4100 feet.
