A jet airliner moving initially at 693 mph (with respect to the ground) to the east moves into a region where the wind is blowin
Nesterboy [21]

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

v=v_{a}+v_{w}

We need to calculate the new speed of the aircraft with respect to the ground

Using formula for velocity

v=\sqrt{(v_{a})^2+(v_{w})^2+2v_{a}v_{w}\cos\theta}

Put the value into the formula

v=\sqrt{(693)^2+(798)^2+2\times693\times798\cos37}

v=1414.3\ mph

Hence, The new speed of the aircraft with respect to the ground is 1414.3 mph.

A force of 25 N acts on an object at an angle of 30 degrees above the horizontal. How much work does the force do if the object
8_murik_8 [283]
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.
