Velocity is the displacement of an object over the amount of time. It is not the same as speed. If an object travels 4 miles forward and then 4 miles back all in one hour, its speed is 8 mph. However, displacement is the difference between the final position and the initial position. So in this case, the average velocity would be 0 because its final and initial positions were the same.
Answer:
In a nutshell, units of A and B are and , respectively.
Explanation:
From Dimensional Analysis we understand that and have length units () and have time units (). Then, we get that:
(Eq. 1)
(Eq. 2)
Now we finally clear each constant:
In a nutshell, units of A and B are and , respectively.
Force = mass times acceleration
F = 21000 x 36.9 = 774900
Therefore, 774900N force is required.
