Question

A body is thrown with a velocity of 9.8 m/s making an angle of 30° with the horizontal. It will hit the ground after a time: (A) 1.5 s (B) 1 s (C) 3s (D) 2s

The time of flight =(2u sin θ /g) =(2× 9.8× sin 30° /9.8)=1 s

Q. A body is thrown with a velocity of 9.8 m/s making an angle of $30^{\circ}$ with the horizontal. It will hit the ground after a time:

1.5 s

1 s

3s

2s

The time of flight $= \frac{2 u s i n θ}{g}$ $= \frac{2 \times 9.8 \times s i n 30 ^{\circ}}{9.8} = 1 s$
