I could really use some help with this problem that I can't seem to solve after spending several hours on it.

A soccer player kicks a ball from level ground so that it will reach its maximum range, which is Rmax. How high is the ball when its horizontal distance from the starting point is 1/2 Rmax? How high is the ball when its horizontal distance from the starting point is 3/4 Rmax? (Ignore wind resistance).

For example, every other constant we come across in natural science is irrational number in our number system. e.g Cicle is natural shape, Pi is irrational. Gravity is natural, G is irrational. Electrostatic force is natural, Epsilon and charge measured on electron is irrational and so on.

Will it not be worthwhile to find why all such natural constants are irrational in our number/measurement system?

According to the theory of relativity, the answer is NOT, but what do you think on this matter?

Calculate the force of gravity between the earth(mass=6*10^24kg) and the sun (mass=2*10^30kg, distance 1.5*10^11m)

My work thus far:

. F= G (m1+m2)/d^2

F= (6*10^24) (2*10^30)/ (1.5*10^11) ^2

how do I figure out 10^24...10^30.....10^11 etc...and do I need to complete it to that extent?

the sun how would the light intenisty compare with that on eart. I say the light would be 4x as far away. How would it compare to a planet that is 10x as far away. I think the light would be 1/100th away as opposed to 1/4th. Am I correct? (Inverse-square law)

I have my own speculation but not sure if I am correct. So tell me what you think.

I'm a lightweight in physics, but from what i have learnt so far is that light has properties of both a particle and of an EMF.
We see the characteristic of light which resembles that of a particle when it is passing through a medium so reduced in velocity.

Is it possible to reduce light to a velocity of 0, if so, would it behave as a particle?

If 'h' is the level of the water when the wooden block is placed with the coin on its top and if 'l' is the height of the water displaced by the wooden block, then, the options are:
(a) l decreases and h increases
(b) l increases and h decreses
(c) both l and h increase
(d) both l and h decrease
choose any one of the 4 options as your answer
