  • When a projectile projected at angle of   with the Horizontal and having initial velocity

When a projectile projected at angle of  60^{\circ} with the Horizontal and having initial velocity 20 \mathrm{~m} / \mathrm{sec}. find the velocity of Projection at  t=1.7  sec from starting  (g=10 \mathrm{~m} / \mathrm{sec})

Option: 1

10 \mathrm{~m} / \mathrm{sec} \\


Option: 2

20 \mathrm{m} / \mathrm{sec} \\


Option: 3

30 \mathrm{~m} / \mathrm{sec} \\


Option: 4

zero

T= \frac{24 \sin \theta}{g}=\frac{2 \times 20 \sin 60^{\circ}}{g} \\
=\frac{4 \sqrt{3}}{2}=2 \sqrt{3}=2 \times 1.7

=3.4 \mathrm{sec} .
t=1.7 \mathrm{sec}, Half of time of flight


At maximum height
V_y=0, V_x=v_x .

velocity at  t=1.7 \mathrm{sec}
V x=v \cos 60^{\circ}=20 \times \frac{1}{2}

                                =10 \mathrm{~m} / \mathrm{sec}
