Question

a stone at rest is dropped from a height and falls freely under gravity. Calculate the distance covered by it in 3 seconds also find the final velocity when it strikes the ground

Answer 1

Answer:

4.9*9

Explanation:

u = 0

a=g

S=ut+1/2at2

since u is 0 'ut' will be 0

so      S=1/2 *9g

g=9.8

when we solve it we get 4.9*9
