Question

an aircraft with the mass of 300000kg is flying at an altitude of 2000m with a speed of 100m/s
what is the kinetic energy of the aircraft ​

Answer 1

Answer:

Explanation:

K.E is 1/2 mv^2

Therefore KE is 300000×10000×1/2

=1500000000J

= 1500000KJ

Potential energy is mgh

Therefore PE is 300000×9.8×2000

=5,880,000,000J

=5880000KJ

Answer 2

Answer:

1.5*10^9 joules.

Explanation:

Kinetic energy = ½ mv².

K.E= ½ *300000*(100)².

K.E= 150000 * 10000.

K.E= 1500000000 joules.
