When its 100-hp engine is generating full power, a small airplane with mass 700 kggains altitude at a rate of 2.5 m/s. What frac

snow_lady [41]

For the given problem it is necessary to recap the concepts about Power, that is, is the rate of doing work or of transferring heat, i.e. the amount of energy transferred or converted per unit time.

The equation for power can be written as

$P = FV$

Where,

F= Net Force

V =Velocity

By the second newton law, force can be:

F = mg

Where m means the mass and g the gravity acceleration.

We can also write the equation as,

P = mgv

Replacing the values

P = 700*9.8*25

P = 17.15kW

Tenemos unidades en dos sistemas diferentes, por lo que convertimos los HP a Sistema internacional y tenemos que

1hp = 0.746kW

Then the fraction $\eta$ is,

$\eta = \frac{17.15kW}{0.746kW}$

$\eta = 22.989$

Therefore the fraction of the engine power is being used to make the airplane climb is 22.984%

Dmitrij [34]

Complete Question

The cars of a roller-coaster ride have a speed of 19.0 km/h as they pass over the top of the circular track. Neglect any friction and calculate their speed v when they reach the horizontal bottom position. At the top position, the radius of the circular path of their mass centers is 21 m, and all six cars have the same mass.V = -18 m What is v?X km/h

Answer:

$v=23.6m/s$
