Question

when body falling from height cover 20 m within 1.2 sec find velocity​

Answer 1

first follow me then I give answer

Answer 2

Answer:

Initially velocity(u)=0

Distance covered(s)=20m

Time taken(t)=1.2 sec

Acceleration(g)(gravity)=10

Final velocity(v)=?

Explanation:

v^2=u^2 +2as/v^2=u^2 +2gs

v^2=0+2*10*20

v^2=400

v=√400

v=20

I'm not totally sure about the answer cause I am not the best in Physics
