Answer: A
Explanation: We can use the concept of conservation energy which implies that the kinetic energy of the froghoppers equals it potential energy from the ground level.
Where potential energy = mgh
Where m = mass of the object , g = acceleration due gravity and h = height from ground level.
The value of potential energy will reduce when the height is inclined at an angle.
Let us assume equal mass for both froghoppers, say m , g = 10 m/s^2 and a value of h.
For the first froghopper, potential energy = m×9.8×h = 9.8 mh
For the second froghopper, potential energy = m×9.8×hsin58 ( hsin58 is the vertical componet of height h inclined at angle 58),
potential energy = 8.3109 mh
As we can see , froghopper A has more potential energy than froghoppers B which implies that A has more kinetic energy than B
