question_answer 10)

Here . (i) During first 10 s, the horizontal component of the velocity is   From 10 s to 11 s (i.e., for 1 s), the vertical component of the velocity is    Resultant velocity,   The direction of resultant velocity with the horizontal is given by  or . (ii) As there is no horizontal acceleration, the only acceleration is vertical.  Vertically downward acceleration .
