The speed of the ball is B. 5 meters per second
Explanation:
For an object in uniform motion (= at constant velocity), the speed can be calculated using the equation

where
v is the speed
d is the distance covered
t is the time taken
For the ball in this problem:
d = 50 m is the distance covered
t = 10 s is the time taken
Substituting, we find the speed:

PE equals KE when KE is 50%.
Like below:
E = PE + KE
E = 50 + 50
E = 100.
Remember, both KE and PE always have to add up to 100 so that is why PE is equal to KE when KE is 50% of energy.
Hope I helped. :)
True
