The marble is thrown horizontally...since it is thrown // to x-axis
As
v=u+at
=10+(2*10)
= 30 m/s
Akash Anand Wrong Answer..and approach as well, think in 3DDwijaraj Paul Chowdhury Is the answer 10root 2?....because the motion of the projectile is in 2-D onlyAkash Anand No.. its again wrong
996is the answer 10m/s
Dwijaraj Paul Chowdhury How?Swarna Kamal Dhyawala sir wat is the answer to this question
591Is the answer 10m/s ??
Akash Anand yeah ..this is the answer ..try to provide the solution481Sir my answer is coming as 10/root2,please provide the correct solution
466it is 10 m/s ...
vyis const. thruout = 10/√2
vx is connst ant ly changing thru out
from 10/√2 to -10/√2 (v=→≡u-gt)
so final magnitude is √(-a)2+ b2 = √(a)2+ b2
=10 ms-1
Himanshu Giria it wud effectivly b g x sin( theta=45 degree.)
x tHimanshu Giria since v=u-gt is applicable for 1_D only ...
