Which receptor cells most directly enable us to distinguish different wavelengths of light?

There are three main types of photoreceptor cells in the retinas of mammals: rods, cones and ganglion cells. Moreover, the ability to distinguish different wavelengths of visible light is the same as the ability to see color. This ability is provided by cone cells. Although cones are less sensitive to light than rods are, they allow us to distinguish different colors.

Since you have not included the experiment situation and the data, of course, i can not give you specific details about it. but i can you with this question.1) i will assume that the motion is projectile (parabolic) motion.2) yes, the horizontal distance depends on the horizontal velocity as, naming vx the horizontal velocity and t the time, it is: x = vx × t3) now, observe that the flight time depends on the vertical velocity as, naming voy the initial vertical velocity, t the time and y the vertical distance before reaching the ground: y = yo + voy×t - gt² / 2.the higher the initial vertical velocity (voy) the longer the object will be flying and so t will be higher in the equation for the horizontal distance.that explains the relationship between the horizontal distance and the horizontal velocity.
