Look at it this way:
Every time the plane flies through 400 miles of air,
the air moves it 40 miles backwards.
So it only covers 360 miles of ground in an hour.
Answer:
The car needs nearly 2.6 s
5.678 * 10^10 is the answer
Answer:C
Explanation:
Given
Overload mass =90 Pounds
and 1 Pound=0.453 kg
90 Pounds=40.823 kg
Density of Gasoline 
Volume of Gasoline for this mass 
and 
is equal to 264.172 Gallon
therefore 0.05451 m^3 is equal to 14.40 Gallons which is approximately equals to 15 Gallon
Answer:
Acceleration= 1,59 (meters/(second^2))
Direction= NE; 65,22° above the east direction.
Explanation:
Resulting force= ( ((180N)^2) + ((390N)^2) ) ^ (1/2) = 429,53 N
Angle obove the east direction= ((cos) ^ (-1)) (180N / 429,53 N) = 65,22°
Acceleration= Resulting force / mass = (429,53 N) / (270 kg) =
= (429,53 kg × (meters/(second^2))) / (270kg) = 1,59 (meters/(second^2))
