Arunner moves west with an initial velocity of 4 m/s. she accelerates 3 m/s2 for 30 seconds. the runner’s final velocity is

Runner’s final velocity is 94 m/s

Explanation:

It is given that,

The initial velocity of the runner, u = 4 m/s

Acceleration of the runner, a = 3 m/s²

Time taken, t = 30 seconds

We have to find the final velocity of the runner. It can be calculated using first equation of motion as :

Where

v is the final velocity of the runner

v = 94 m/s

Hence, the final velocity of the runner is 94 m/s

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
