Question

A body is dropped from hight h at latitude a in the northern hemisphere .What is the distance it strike's the ground

Answer 1

Explanation:

Correct option is

A

5m/s

First body initial speed u=0

Final speed =3m/s

Second body initial speed=4m/s

Body is dropped from height h

So a=g=10m/s2

v2=u2+2gh

32=0+20h 

9=20h

h=209

Second object is also dropped from same height.

therefore, h=920

u=4m/s

v2=u2+2gh

v=5m/s
