How does an airplane's kinetic energy and potential energy change as it takes off and lands

1) take off: potential energy equals to 0, kinetic is very high as it's seeped up
2) assending: potential energy grow, kinetic energy depends if pilot accelerates much or not, but normally he is, so there is some kinetic energy as well but less than on take off
3) flying: potential energy reaches it's maximum, there is some kinetic energy as aircraft flys
4) descending: potential energy goes down, kinetic increase due to gravity.
5) landing: potential energy is zero, kinetic is max until pilot press brakes.

John runs for 10 mins at a uniform speed 9kn/h. At what speed should he run for the next 20mins so that theaverage speed comes t

kolbaska11 [484]

Answer:

13.5 km/h

Explanation:

John runs for 10 min at 9 km/h, then 20 min at v. He will have run a total of 30 min at 12 km/h.

Therefore:

(30 min) (12 km/h) = (10 min) (9 km/h) + (20 min) v

v = 13.5 km/h

How much more mass does 12Mg have than 12g

Masja [62]

Explanation:

Given that,

First mass, $m_1=12\ Mg$

Other mass, $m_2=12\ g$

We know that,

1 Megagram (Mg) = 10⁶ grams (g)

So, $1\ g=10^{-6}\ Mg$

Using unitary method,

$m_2=12\ g=12\times 10^{-6}\ Mg$

So, $m_1-m_2=12\ Mg-12\times 10^{-6}\ Mg$

$m_1-m_2=10^{-6}$

So, the mass of 12 Mg is $10^{-6}$ more than 12 grams. Hence, this is the required solution.

If an object has 110 J of potential energy when it is 40 m off the ground, what is it’s potential energy when it is 200 m off th

IgorC [24]

Answer:

550 J

Explanation:

Given:

PE = 110 J

h = 40 m

h' = 200 m

To Find:

PE' = ?

Solution:

PE = mgh

PE = W x h

110 = W x 40

Multiplying by 5 on both sides,

550 = W x 200

550 = W x h'

550 = PE'

Therefore, PE' = 550 J
