Answer:
a. same
b. less
c. less
Explanation:
you can use the position, time, acceleration equation
xf=xi + vi*t+(at^2)/2
you can say the final distance will greater for X than Y
using acceleration for gravity a=9.81m/s^2
a. both X and Y will have the same acceleration due to gravity
b. to solve for final speed vf=vi+gt
since the initial velocity is 0 and X will take longer to fall, Y will hit the ground with less speed
c. as mentioned before, X will take longer to fall; therefore Y will have less time of descent.
