A student kicks a soccer ball with an initial velocity of 12.0 m/s at a fence at an angle θ = 53 degrees, which is a height 3.5 meters and is a distance of 5.0 meters away from where they kicked the ball. The ball hits nothing in flight while in flight and air resistance is negligible. sin 53 degrees = 0.80
cos 53 degrees = 0.60
tan 53 degrees = 1.33

A. Determine the initial horizontal and vertical velocity vox and voy of the ball.
B. Determine the time it takes for the ball to reach the fence.
C. Will the ball hit the fence? If so, how far below the top of the fence will it hit? If not, how far above the top of the fence will it pass?
D. The student repeats the kick in a flat field with no fence, it lands at the same vertical
position it was kicked from.
i. How much time does the ball spend in the air?
Ii. Determine the horizontal distance the ball will travel.

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.

scattering of light by tiny particles in air to produce the colors we see on sky, is dependent on the following factors:

(i) wavelength of light

(ii) size of the scattering particle  

(iii) distance traveled by light through the atmosphere.

according to rayleigh's law of scattering, the amount of scattering is inversely proportional to the fourth power of its wavelength. shorter the wavelength, greater is its scattering. hence violet/blue light is scattered more than red.

sun's light is a composite light ( visible light) with wavelengths in the range 400 nm (violet) to 700 nm (red). as sunlight passes through our atmosphere, the molecules of air scatter light according to their wavelengths. during sunrise and sunset, the sun's position is below the horizon. hence light from the sun travels a greater distance in the atmosphere when compared to its position a noon.

as sunlight enters the earth's atmosphere, blue light is scattered away and at the end of its journey in the sky, only red and orange wavelengths remain in the beam.

hence at sunrise and sunset, the sky appears reddish orange.

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.
