State the correct expression for the total time of flight

T

of a projectile launched from ground level with initial speed

v_0

at an angle

\theta

to the horizontal (neglect

g

variation). (a)

T=\dfrac{2v_0\cos\theta}{g}

(b)

T=\dfrac{2v_0\sin\theta}{g}

(c)

T=\dfrac{v_0\sin\theta}{g}

(d)

T=\dfrac{2v_0\tan\theta}{g}
