A dog chases a car, running 825 m west in 6.22 s. What is the average velocity of the dog?

132.64m/s

Explanation:

Averagevelocity= distance/time

From the question, the distance d = 825m

time t = 6.22 secs

Using the above formula

We have

average velocity = 825/6.22

= 132.64m/s

i believe the answer is a

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
