Answer:
Explanation:
Given
winning car accelerates with a and its final velocity is v
considering they both start from rest
time taken by winning car is
v=u+at
where u=initial velocity
a=acceleration
t=time


Now loosing car is accelerating with 
Distance traveled by loosing car in time t



Thus distance d traveled by loosing car is given by 
Answer:
21.49 hrs
Explanation:
it is the longest day of daylight due to Alaska being closest to the au. at the time
Explanation:
This question is not feasible. There is no way to calculate the energy needed because the question is missing the final temperature
Work = (force) x (distance)
Power = (work) / (time)
Knowing force, distance, and time, it looks like
you can calculate both <em>work and power</em>.
But that's not all !
-- <u>Speed</u> = (distance) / (time)
-- <u>Impulse</u> = change in momentum = (force) x (time)
