Following Newton's Laws of Motion
h+=+1%2F2+%2A+gt%5E2 where g = acceleration due to gravity= 10m%2Fs%5E2 and t is the time
So we get +h+=+1%2F2+%2A+10+%2A+%282.2%29%5E2
I'll leave it to you to solve
And Newton was good enough to give this answer as well
V%5E2+=+2gh
Please substitute to find the answers
