Acceleration - gravity

What is the gravitational acceleration if a body with a mass of 5.8 kg fell from 68 metres and hit the ground at a speed of 60 km/h?

Final Answer:

a =  2.0425 m/s2

Step-by-step explanation:

m=5.8 kg h=68 m v=60 km/h m/s=60:3.6  m/s=16.66667 m/s  h = 21 a t2 v = a t  h = 21 v t  t=v2 h=16.66672 68=25204=8.16 s  a=v/t=16.6667/8.16=2.0425 m/s2
