You are out on an early morning jog when you see a family of squirrels in a tree that lies directly in your path. A squirrel on a branch 20 m high in the tree drops an acorn directly above your head as you run with speed 1.5 m/s beneath the squirrel's position. How far behind you does the acorn hit the ground?

The acorn hit the ground 3 m far away from me.

Explanation:

Here ,

time taken by the  acorn to fall be 't',

Height of the tree is 20m ,

so

Acceleration due to gravity is -

Initial velocity is 0 ,so  u=0

According to the second equation of motion ,

sec.

Distance travelled by you in 2 sec

Put speed=  1.5m/s² and time = 2sec

 Hence , the acorn hit the ground 3m far away from me.            

good for her? ? where is the question?
