Afire helicopter carries a 700-kg bucket of water at the end of a 20.0-m long cable. flying back from a fire at a constant speed of 40.0 m/s, the cable makes an angle of 38.0° with respect to the vertical. determine the force exerted by air resistance on the bucket.

F = 50636.873 N

Explanation:

given,

bucket of water =  700-kg

length of cable = 20 m

Speed  = 40 m/s

angle of the cable = 38.0°

let air resistance be = F

tension in rope be = T

T cos 38° = m×g..................(1)

..........(2)

equation (1)/(2)

           F = 50636.873 N

Hence the force exerted on the bucket is equal to F = 50636.873 N

the answer is mosques. they are an important part of islamic culture.
