An object starts from rest and falls freely near earths surface for 3.00 seconds. calculate the final speed of the object

Given:

u(intial velocity)=0

a(acceleration)=9.8 m/s^2(as it is a free falling object acceleration is due to gravity)

t= 3 seconds

In order to find the final velocity v

We know that

v= u+at

Where v is the final velocity measured in m/s

u is the initial velocity measured in m/s

a is the acceleration measured in m/s^2.

t is the time taken to fall down measured in seconds

Now substituting the given values in the above formula we get

v=u +at

v=0+(9.8 x 3)

v=29.4m/s

Thus the final velocity is 29.4 m/s.

answer: the direction of the wind is expressed as the direction from which the wind is blowing. for example, easterly winds blow from east to west, while westerly winds blow from west to east.
