Question

Two balls are thrown vertically, both at initial speed of 10.0 m/s from height off 60.0 m above the ground. Ball A is thrown upward, while Ball B is projected downward, which ball will hit the ground first?

Answer 1

Answer:

Ball b

Explanation:

because it is thrown downward

Answer 2

Answer:

Explanation:

h1= -ut+½at²

h2=ut+½at²

Taking velocity against the gravity negative from the equations we can compute that ball b will reach first
