Question

A seagull flies at a velocity of 7.00 m/s straight into the wind.
(a) If it takes the bird 17.0 min to travel 6.00 km relative to the earth, what is the velocity of the wind?
(b) If the bird turns around and flies with the wind, how long will he take to return 6.00 km?

Answer 1

A dog running in an open field has components of velocity
v
x
= 2.7
m/s
and
v
y
= -1.7
m/s
at time
t
1
= 11.8
s
. For the time interval from
t
1
= 11.8
s
to
t
2
= 22.6
s
, the average acceleration of the dog has magnitude 0.49
m/
s
2
and direction 35.5
