A frog leaps vertically into the air and encounters no appreciable air resistance. Which is true about frog's motion?
A.On the way up its acceleration is 9.8m/s^2 upward, and on the way down its acceleration is 9.8downward.
B.On the way up and on the way down its acceleration is 9.8m/s^2 downward, and at the highest point its acceleration is zero.
C.On the way up, on the way down, and at the highest point its acceleration is 9.8m/s^2 downward.

Best ResponseYou've already chosen the best response.0c is right as at the highest point yes velocity becomes zero but change in velocity need not be zero...and always acceleration is 9.8m/s^2
