Answer:
The fastest thing in the whole universe is the speed of light in a vacuum (like outer space!), clocking in at a great 2.99 x 108 m/s. Light travels in waves, and we call this traveling propagation. Propagation of waves has both a speed and a direction, called the velocity. The velocity of light changes depends on the material it travels through.

Answer:
meter per second square
Explanation:
Given
Height ,h 
m
Radius, r 
m
Distance travelled, 
m
Since, the stone is released and it falls towards the sky, its initial velocity is zero
As per equation
, we will evaluate "t"
Substituting the given values in above equation, we get
Velocity
centripetal acceleration
