A body of mass 10 kg is projected at an angle of 45° with the horizontal. The trajectory of the body is observed to pass through a point (20, 10). If T is the time of flight, then its momentum vector, at time t =T/√2}, is _________.
[Take g = 10 m/s2]
1
\(100 \hat{i}+(100 √{2}-200) \hat{j}\)
2
\(100 √{2} \hat{i}+(100-200 √{2}) \hat{j}\)
3
\(100 \hat{i}+(100-200 √{2}) \hat{j}\)
4
\(100 √{2} \hat{i}+(100 √{2}-200) \hat{j}\)
