A ball is thrown upwards and returns to the same position, with negligible air resistance acting on it. Compared with its original speed after release, its speed when it returns to the same position is about
a.) half as much
b.) the same
c.) twice as much
d.) four times as much

Answer 1

think energy

Answer 2

same

Answer 3

I think B. This is my explanation. Drawing a picture helps. Since an object in free fall's at 10m/s, throwing an object upward will also reduce by 10m/s.
