Answer:
velocity of the plane = 274 miles/hour at 30.9⁰
velocity and direction of the wind = 26.7 miles/hour at 20.8⁰
Explanation:
Let the velocities be resolved using the vector method.
Let the x - axis be directed to the east
similarly, we shall direct the y axis upwards- to the north
Airspeed is given by
300 mil/h. (30⁰) = 300 (cos30⁰i + sin 30⁰j
plane relative to ship
= 12 miles/hour
= 12j
- velocity of the plane is given by:
v =
+ Vijb
= -12 j + 280 (cos 33⁰i + sin 33⁰j)
= 234.83 i + 140.50 j
= 274 miles per hour
- velocity of the wind is given by the following equation:

= 234.831 + 140.50J - 300(cos 30⁰i + sin 30⁰j)
= -24.98i - 9.50 j
= 26.7 miles per hour at 20.8⁰

Answer:
MRR = 1.984
Explanation:
Given that
Depth of cut ,d=0.105 in
Diameter D= 1 in
Speed V= 105 sfpm
feed f= 0.015 ipr
Now the metal removal rate given as
MRR= 12 f V d
d= depth of cut
V= Speed
f=Feed
MRR= Metal removal rate
By putting the values
MRR= 12 f V d
MRR = 12 x 0.015 x 105 x 0.105
MRR = 1.984
Therefore answer is -
1.944
