When Galileo got ahold of a little telescope ... no more than
a kid's toy today ... he soon turned it towards the night sky. 
The story says that he was the first one to do that.  Apparently
everyone else who had these things used them to look at their
neighbors' windows.  Anyway, When Galileo looked at Jupiter,
he saw four tiny dots.  As he watched them night after night, he
saw that the four dots always stayed with Jupiter, but got nearer
and farther from it.  He eventually realized that they were small
bodies in orbit around Jupiter.  And then ... because he was Galileo ...
he made the big intellectual jump:  He reasoned that if there were
smaller bodies in orbit around Jupiter, then Jupiter and the other
planets might also be in orbit around something, and not necessarily
around the Earth.  He understood this as evidence that the sun is
the center of the solar system.

Answer:

15.3 s and 332 m

Explanation:

With the launch of projectiles expressions we can solve this problem, with the acceleration of the moon

    gm = 1/6 ge

    gm = 1/6  9.8 m/s² = 1.63 m/s²

We calculate the range

    R = Vo² sin 2θ  / g

    R = 25² sin (2 30) / 1.63

    R= 332 m

We will calculate the time of flight,

   Y = Voy t – ½ g t2  

   Voy = Vo sin θ

When the ball reaches the end point has the same initial  height Y=0

0 = Vo sin  t – ½  g t2

0 = 25 sin (30)  t – ½ 1.63 t2

0= 12.5 t –  0.815 t2

We solve the equation

0= t ( 12.5 -0.815 t)

 t=0 s

t= 15.3 s

The value of zero corresponds to the departure point and the flight time is 15.3 s

Let's calculate the reach on earth

R2 = 25² sin (2 30) / 9.8

R2 = 55.2 m

R/R2 = 332/55.2

R/R2 = 6

Therefore the ball travels a distance six times greater on the moon than on Earth

What makes speed, velocity, acceleration, distance, and time different?​
LekaFEV [45]

Explanation:

  • Speed is the rate of change of distance with time.

            Speed = \frac{distance}{time}

  • Velocity is given as the displacement per unit of time:

             Velocity = \frac{displacement}{time}

Speed and velocity are similar but speed is a scalar quantity while velocity is a vector quantity. Speed has magnitude but does not point towards a specific direction. Velocity shows both magnitude and direction and it is a vector quantity.

  • Acceleration is given as the change in velocity with time. It is a vector quantity:

                Acceleration = \frac{change in velocity}{time}

  • Distance is how far a body moves. It is scalar quantity.
  • Time is the duration of an event. It is a scalar quantity.
