A particle is projected from the ground with an initial speed $\upsilon $ at an angle $\theta $ with horizontal. The average velocity of the particle between its point of projection and highest point of trajectory is

  • A

    $\frac{\upsilon }{2}\sqrt {1 + 2\,\,{{\cos }^{2\,}}\theta } $

  • B

    $\frac{\upsilon }{2}\sqrt {1 + {{\cos }^{2\,}}\theta } $

  • C

    $\frac{\upsilon }{2}\sqrt {1 + 3\,\,{{\cos }^{2\,}}\theta } $

  • D

    $\upsilon \,\cos \,\theta $
