Answer:
The new speed of the aircraft with respect to the ground is 1414.3 mph.
Explanation:
Given that,
Angle = 37°
Velocity of jet airliner = 693 mph
Velocity of wind = 798 mph
We know that,
The new velocity of the aircraft with respect to the ground

We need to calculate the new speed of the aircraft with respect to the ground
Using formula for velocity

Put the value into the formula


Hence, The new speed of the aircraft with respect to the ground is 1414.3 mph.
Answer:
Radiation , Conduction and Convection
Explanation:
Those are the ways heat is transferred
We can find the x-component of the force vector, so Fx = 25N(cos30). Then, we can sub this into the work equation W = Fs or W = Fd.
Therefore, W = (25N(cos30))(3m) = 64.95 J.
With sig figs, it is 60 J.
