As part of a NASA experiment, golfer Tiger Woods drives a golf ball on the moon, where g = 1.60 m/s2. He launches a golf ball wi

th a speed of 285 km/h, at an angle of 42° with the horizontal. What horizontal distance will his drive travel before landing back on the surface of the moon. Ignore the curvature of the moon.​

Answer:

Horizontal distance, R = vo2 sin(2x45)/g

v = 285 km/h = 79.17 m/s

R = 79.172 x 1/1.6

R = 3917 m

R = 3.9 km

What is the magnitude of the gravitational force of attraction to Jupiter exerts on IO
kotegsom [21]

The gravity force between Jupiter and Io will be 6.343 × 10²² N.

<h3>What is Newton's law of gravitation?</h3>

Newton's law of gravity states that each particle having mass in the universe attracts each other particle with a force known as the gravitational force.

Given data;

Mass of Jupiter,\rm m_j = 1.9 \times 10^{27} \ kg

Mass of moon of Jupiter,\rm m_{i_0}= 8.9 \times 10^{22} \ kg]

The gravitational constant is,\rm G =  6.67 \times 10^{-11 } \ m^3  kg^{-1}  s^{-2}

Distance between Jupiter and Io, R = 421,700 km = 4,217,00,000 m

The gravitational force is proportional to the product of the masses of the two bodies and inversely proportional to the square of their distance.

The gravitational force is found as;

\rm F = G \frac{ m_J m_{I_0}}{R^2} \\\\\ F = (6.67\times 10^{-11}) \frac{( (1.9\times 10^{27})\times (8.9\times 10^{22} )} { (421700000)^2}\\\\ F_g = 6.343 \times 10^{22} \  N

Hence, the gravity force between Jupiter and Io will be 6.343 × 10²² N.

The complete question is

"Jupiter has a mass of 1.9 × 1027 kg, and its moon Io has a mass of 8.9 × 1022 kg. Their centers are separated by a distance of 421,700 km what is the force of gravity acting on Io? "

On Earth, 1 kg = 9.8 N = 2.2 lbs. On the Moon, 1 kg = 1.6 N = 0.37 lbs. Use these relationships to answer the following question
romanna [79]

Answer:

(a) 490 N on earth

(b) 80 N on earth

(c) 45.4545 kg on earth

(d) 270.27 kg on moon

Explanation:

We have given 1 kg = 9.8 N = 2.2 lbs on earth

And 1 kg = 1.6 N = 0.37 lbs on moon

(a) We have given mass of the person m = 50 kg

As it is given that 1 kg = 9.8 N

So 50 kg = 50×9.8 =490 N

(b) Mass of the person on moon = 50 kg

As it is given that on moon 1 kg = 1.6 N

So 50 kg = 50×1.6 = 80 N

(c) We have given that weight of the person on the earth = 100 lbs

As it is given that 1 kg = 2.2 lbs on earth

So 100 lbs = 45.4545 kg

(d) We have given weight of the person on moon = 100 lbs

As it is given that 1 kg = 0.37 lbs

So 100 lbs \frac{100}{0.37}=270.27kg

What does a mechanical advantage less then one mean? What is gained?
GrogVix [38]
A mechanical advantage less than ' 1 ' means the output <u>force</u> is less than the input
force. But <em>distance</em> is gained ... the load moves farther than the driving force moves.

An example of all this is a big father and his little 4-year-old daughter playing
on the see-saw in the park.  He adjusts the board so that he's much closer
to the pivot than she is, and that way, their weights can balance each other.

It's set up so that the mechanical advantage from him to her is less than ' 1 '.
Now, look at what happens when Dad sits down on his end of the see-saw,
and pushes it down with his 180 pounds of force.  At the other end, the board
is barely lifting her with a force of just 30 pounds.  BUT ... as he sinks down
only 1 foot against his end of the board, <em>her</em> end rises 6 feet off the ground.

z jaka maksymalna predkoscia porusza sie przez krotka chwile rowerzysta jezeli dysponuje moca maksymalna 420w i przy predkosci z
qwelly [4]

Answer:

12 m/s

Explanation:

English Translation

At what maximum speed is the cyclist traveling for a short time if he has a maximum power of 420W and at this speed he must overcome the resistance 35N.

The Power, P, expended by a moving body with velocity, v, moving against a resistive force of F is given as

P = Fv

P = 420 W

F = 35 N

v = ?

420 = 35v

v = (420/35) = 12 m/s

In Polish/Po polsku

Moc P, wydana przez poruszające się ciało z prędkością v, poruszająca się przeciw sile oporu F, jest podana jako

P = Fv

P = 420 W

F = 35 N

v = ?

420 = 35v

v = (420/35) = 12 m/s

Hope this Helps!!!

Mam nadzieję że to pomoże!!!
