Assume your car reaches a speed of 21.7 m/s at a steady rate for 5.05 s after the light turns green. (a) what distance have you traveled during this time? (b) what is your average speed during this time?

The distance and average speed are 54.79 m and 10.85 m.

Explanation:

Given that,

Speed = 21.7 m/s

Time = 5.05 s

(a). We need to calculate the distance

Firstly we will find the acceleration

Using equation of motion

Where, v = final velocity

u = initial velocity

t = time

Put the value in the equation

Now, using equation of motion again

For distance,

The distance is 54.79 m.

(b). We need to calculate the average speed during this time

Where, D = total distance

T = time

Put the value into the formula

Hence, The distance and average speed are 54.79 m and 10.85 m.

b mirrors submit a iisner? e. for which optical devices does d sometimes have a positive value? o a a and b o b. a and c o c. b and d 0 d. b and cb

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.
