A man jumps horizontally from the top of a building that is 20.0m high, and hopes to reach a swimming pool that is at the bottom
Oliga [24]

Answer:

5 m/s

Explanation:

Given that the hight of the building, h= 20.0 m

The horizontal distance of the swimming pool from the building, d=10 m

As the man jumps horizontally, so the vertical velocity at the time of jumping is 0.

Let s be the initial horizontal velocity of the man at the time of jumping.

As the gravitational force always acts in the vertical direction, so, it does not change the horizontal speed.

So, the horizontal velocity, s, remains constant throughout the motion.

If t be the time of flight, then s=10/t \cdots(i)

Now, applying the equation of motion in the vertical direction,

s=ut+\frac 1 2 at^2

where u is the initial velocity, t is the time of flight, a is the acceleration, s is the displacement.

Here, putting s= 20 m, u=0, a=g=9.81 m/s^2 in the equation of motion, we have

20=0\timest+\frac 1 2 (9.81)t^2 \\\\\Rightarrow 20 = \frac 1 2 (9.81)t^2 \\\\\Rightarrow t^2 = (20\times2)/9.81 \\\\

\Rightarrow t = 2 seconds (approx)

Now, put t=2 in the equation ( we have

s=10/2=5m/s

Hence, the man must jump with 5 m/s horizontally to reach the pool.

What was the first evidence that gravity outside our solar system worked the same way as it does inside?
Julli [10]

The first evidence that gravity outside our solar system worked the same way as it does inside is that Herschel measured the two stars that make up the Castor system moved around each other

<h3>What is a Solar system ?</h3>

The Sun, eight planets, their moons, comets, asteroids, meteoroids, and dwarf planets make up a solar system, which revolves around the Sun. Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune are the eight planets that revolve in a particular order around the Sun.

  • Although there are more than 3,200 other stars in our galaxy with planets around them, our solar system is the only one that is formally referred to as a "solar system."

  • The closest stellar system to our solar system, Alpha Centauri, is one of the brightest stars in the southern skies and is only 4.3 light-years away.

Pauline is going on a picnic and bringing some sandwiches. She wants to keep the sandwiches cold for as long as possible by putt
Alja [10]

Answer:

The correct answer is plastic.

Explanation:

To keep sandwiches cold as long as possible by putting them in a cooler the best material is plastic. The plastic is a thermal insulator used for different uses. One of them is to maintain the temperature in closed containers. Metal and aluminum allow the temperature to flow more easily and glass is not a suitable material for building the cooler.

Have a nice day!
