(ii) Upon reaching the water, how does the speed of the smaller child compare with that of the larger child is?

a. It is greater. b. It is less. c. The two speeds are equal.

(iii) During their motions from the platform to the water, how does the average acceleration of the smaller child compare with that of the larger child? a. It is greater. b. It is less. c. The two accelerations are equal.
