The net speed due west is = distance traveled in west / time taken = 120/0.5 = 240 km/h.
so airspeed due west is = net speed - speed of plane = 240-220= 20 km/h.
airspeed due south is = distance traveled in west / time taken= 20/0.5= 40 km/h.
the magnitude of the wind velocity = √[(airspeed due south )² + (airspeed due west)²] = √ ( 40^2 + 20^2 ) = 44.72 km/h
the angle of airspeed south of west is tan⁻¹ ( airspeed due south / airspeed due west )= tan⁻¹(40/20)=63.43 degrees.
if wind velocity is 40 km/h due south, her velocity should have 20 km/h component in north.
so component west = sqrt ( 220^2 - 40^2 ) = 216.33 km/h.
the angle north of west is arctan( 40/216.33 ) = 10.47 degrees.
Answer:
The gravitational potential energy, P.E = 3345484.8 J
Explanation:
Given,
The mass of the person, m = 64 kg
The elevation of the village, h = 5334 m
The gravitational potential energy is the energy possessed by the body due to its height from the surface of the Earth at sea level.
Therefore, the gravitational P.E at height h above sea level is given by the relation
<em>P.E = mgh joules</em>
Substituting the given values,
P.E = 64 kg x 9.8 m/s² x 5334 m
= 3345484.8 J
Hence, the gravitational potential energy associated with the person, P.E = 3345484.8 J
Hope this helps
If u hit oobleck hard it is a solid and when you pick it up and let it fall of your hand it turns into a liquid
By electromagnetic radiation...
hope its helpful...
Particles in the liquid state of matter are close together, yet free to move around one another
