In 1939, Joe Sprinz of the San Francisco Baseball Club attempted to break the record for catching a baseball dropped from the greatest height. He had baseballs dropped from a blimp 240 m above his head in his attempt. How fast was the baseball travelling when it reached the ground?

Explanation:

The baseball will fall with an acceleration of 9.8 m /s²

v² = u² + 2 x a x s

v is final velocity , u is initial velocity , s is height that was travelled by baseball

= 0 + 2 x 9.8 x 240

= 4704

v = 68.58 m /s

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