What is the total energy of a 850 kg sea plane flying at 38 m/s and 20 m above the ocean?

7.8×10^5 J

Explanation:

Total energy = kinetic energy of plane + gravitational potential energy of plane.

Total energy = ((1/2)×m×v²) + (m×g×h)

Here, m is mass of plane, v is velocity of plane, g is acceleration due to gravity and h is height above the ocean.

Now,

Total energy = ((1/2)×m×v²) + (m×g×h)

Total energy = m((v²/2) + (g×h))

Total energy = 850((38²/2) + (9.81×20))

Total energy = 850(722 + 196.2)

Total energy = 7.8×10^5 J

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.

i think the answer is tomato juice? not entirely sure though
