Q1:

If A is the projected area of a vehicle in square metres, V is speed of the vehicles in kilometres per hour and C is a constant, then the wind resistance R to the moving vehicles, is given by

A R = CAV

B R = CAV2

C R = CAV3

D

E R = C2AV

ANS:B - R = CAV2

R = CAV^2.
C = co-efficient of drag (0.6),
A = frontal Area of vehicle,
V = velocity of the vehicle.
