Answer:
frictonal force due to the surface of irregularities
Answer:
The net force on the car is 2560 N.
Explanation:
According to work energy theorem, the amount of work done is equal to the change of kinetic energy by an object. If '
' be the work done on an object to change its kinetic energy from an initial value '
' to the final value '
', then mathematically,
where '
' is the mass of the object and '
' and '
' be the initial and final velocity of the object respectively. If '
' be the net force applied on the car, as per given problem, and '
' is the displacement occurs then we can write,
Given, 
.
Equating equations (I) and (II),
We know, W = F * s
W = mg * s
Here, w = 2 J
m = 180 g = 0.180 Kg
g = 9.8 m/s
Substitute their values into the expression:
2 = 0.180*9.8 * s
1.764s = 2
s = 2 / 1.764
s = 1.13 meter
In short, Your Final Answer is 1.13 m

There is no definite end to earths atmosphere, but technically the border between the outer space and earth gets thinner as you move up from the earths surface. The Karman line is the closest definition there is which describes the end of the earth's atmosphere, it is 100 km above earth's sea level at approximately 1.56 % of total earth's radius. This describes the boundary between the outer space and the atmosphere.
