Answer:

Acceleration, a=14970.05\ km/h^2

Explanation:

Given that,

Initially, the jetliner is at rest, u = 0

Final speed of the jetliner, v = 250 km/h

Time taken, t = 1 min = 0.0167 h

We need to find the acceleration of the jetliner. The mathematical expression for the acceleration is given by :

a=\dfrac{v-u}{t}

a=\dfrac{250}{0.0167}

a=14970.05\ km/h^2

So, the acceleration of the jetliner is 14970.05\ km/h^2. Hence, this is the required solution.

A student runs up a flight of stairs which info is not needed to calculate the rate of the student is doing work against gravity
NikAS [45]

Answer:

B.

Explanation:

Given that a student runs up a flight of stairs which info is not needed to calculate the rate of the student is doing work against gravity A the height of the flight of stairs B the length of flight of stairs C the time taken to run up the stairs D the weight of the student

The rate of doing work is known as power.

Power = work done/time

Work done = energy = mgh

Since energy = mgh

Where mg = weight

And h = height

Time = time taken to run up the stairs.

Time, weight mg and height h will be needed while the Length of the flight is therefore not needed.

The correct answer is B.

How long does a player sit out of a game of handball for committing a second or third foul?
yulyashka [42]

Answer:

Walking’ - If a handball player takes more than three steps without dribbling (bouncing the ball) or holds the ball for more than 3 seconds without bouncing it, shooting or passing, then that is deemed ‘walking' and possession is lost.

'Double dribble’ - Handball players cannot receive the ball and bounce it, then hold the ball, and bounce it again. This is termed ‘double dribble’ and is against the rules.

A ball is thrown straight upward. How does the sign of the work done by gravity while the ball is traveling upward compare with
Vlada [557]
If I’m understanding this. Th reason why the ball can resist gravity’s pull is because the force used to throw it up was greater than gravity’s pull on it. BTW, gravity’s pull is 9.8m/s. So it would have to be greater than that
