Question

When a particle is thrown horizontally, the resultant velocity of the projectile at any time t is given by:
which of these
1) gt                   or
2) √u square + g square t square

Answer 1

$Horizontal\ component\ of\ velocity\ =\ u\ (constant) \\ \\ Vertical\ component\ =\ initial\ velocity\ +\ g t\ =\ 0 + gt = gt \\ \\ Magnitude\ of\ velocity\ =\ \sqrt{u^2 + g^2 t^2}$

Answer 2

Answer:

3

Explanation:

as(horizontal component is constant so=u

and final vertical =initial vertical + gt

so,=gt

magnitude of final velocity vector=(u^2+g^2t^2)^1÷2☺️☺️
