**Answer:**

**Step-by-step explanation:**

using energy conservation law

here

kinetic energy = potential energy

1/2 mv^2 = mgh

v^2 = 2gh or h = v^2 / 2g

a) v = sqrt(2gh) = sqrt(2*9.8*2) = sqrt(39.2) = 6.26 m/s

b) h = v^2 / 2g = 5^2 / 2*9.8 = 25/19.6 = 1.27 m

c) v = sqrt(2gh) = sqrt(2*9.8*0.8) = sqrt(15.68) = 3.95 m/s
