5m/s for the first one??
Wait it can be 15m/s also😓
Q1) B) 5m/s
Q2) 55 sec
Yes both are answer but plz post solution
No, 1 BD
for the first one.
2 cases arise-
I Case- he is initially at point of projection and travels 10 m.In the sane time projectile travels over it’s complete range.Equating the time will give you the velocity as 5m/s.
II Case- he is initially at point of projection.He travels complete range 20m then reverses it’s direction and travels 10 m.In the same time projectile travels 20m.This will give answer as 15m/s.
Yes, I did same
Which one is left
All except 1st
For the last one is the locus is straight line
Bro @PrathamChopra it was told by sir that when we see a another projectile from a projectile we will see that another is moving in straight line . It gives us some example to prove that and said that it’s fact and it never fails.
My sir too have the logic but he told us to write in our way so I left it blank and since then it’s blank.
@fogx_gofx bro can you try 2nd and 3rd.
@PrathamChopra confirm answers
3rd correct. Plz upload solution
