A student uses two identical balls to perform an investigation. The students throws ball a with a horizontal velocity from a height of 10 meters. At the same time another students drops ball b from the same height without horizontal velocity. Neglecting air resistance what can you expect to when the balls will land?

Both objects will land at the same time

Explanation:

The ball projected with a horizontal velocity has a vertical component of velocity which is independent of the horizontal velocity. The horizontal component of the velocity enables the ball to travel a horizontal distance, s The initial component of the vertical download velocity is zero.

Similarly, the object dropped from the height above the ground has an initial vertical velocity zero.

Neglecting air resistance, objects falling near the surface of the earth experience the same acceleration due to gravitational force of the earth, g = 9.8 meters per second squared (9.8 m/s²). So the acceleration is the same for the objects, and consequently their velocity is also increasing at a constant rate. After some time, t, both objects would have been accelerated downwards to the same extent, and would thus land at same time, t.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
