A60 kg man is sitting on the floor of an airplane 8000 m high traveling at 850 km/hr. how much total mechanical energy does he have relative to the reference frame of the plane?

Relative to reference frame of the airplane he's sitting in:

-- Gravitational potential energy = (mass) (gravity) (height)

His height above the airplane is zero, so his GPE is zero.

-- Kinetic energy = (1/2) (mass) (speed)²

His speed relative to the airplane is zero, so his KE is zero.

Mechanical energy = (potential energy) + (kinetic energy)

Mechanical energy = ( 0 ) + ( 0 )

The poor fellow's total mechanical energy is zero .

5.52%

Explanation:

Cost of Furniture= $150,000

discount= 5.25% (120-day note)

To get the exporter's true effective annual financing cost, we have:

=(150,000/147,375) 365/120-1 = 5.52%

Therefore, the exporter's true effective annual financing cost is 5.52%
