Answer:
Explanation:
Lift occurs when a moving flow of gas is turned by a solid object. The flow is turned in one direction, and the lift is generated in the opposite direction, according to Newton's Third Law of action and reaction. Because air is a gas and the molecules are free to move about, any solid surface can deflect a flow.

Answer:
F = 329.27 N
Explanation:
given,
mass of snowmobile = 540 Kg
time = 41 s
intial velocity = 9 m/s
final velocity = 34 m/s
Force = ?
Force is equal to change in momentum per unit time
F = 329.27 N
Force applied to the snowmobile is equal to F = 329.27 N
