A person throws two identical stones from the top of a 200-m high cliff overlooking a lake. Stone 1 is thrown at an angle of 30° above the horizontal with an initial speed of 40 m/s. Stone 2 is thrown at an angle of 30° below the horizontal with an initial speed of 40 m/s. Neglect air resistance.

Immediately before they strike the water, which stone has the greater acceleration?

a. Stone 1.

b. Stone 2.

c. They have the same acceleration.
