The acceleration of gravity is 9.8 m/s² . That means that a falling object
is always falling 9.8 m/s faster than it was falling 1 second earlier.
If an object is not slowed by air resistance, and has far enough to go
so that it's still falling after three whole seconds, then at the end of
three seconds it's falling at
(9.8 m/s²) x (3 sec) = 29.4 m/s
Answer:
A: No because it is nor changing speed or direction
B: Yes because it changes direction even though the speed is constant
