A body is thrown with a velocity of 9.8 ms making an angle of 30∘30^{{}^{\circ}} with the horizontal. It will hit the ground after a time

Options

  1. A3.0 s
  2. B2.0 s
  3. C1.5 s
  4. D1 s

Correct answer

D. 1 s

Step-by-step solution

Time of flight =2usin⁡θg=2×9.8×sin⁡30∘9.8=2×12=1sec⁡=\frac{2 u \sin \theta}{g}=\frac{2 \times 9.8 \times \sin 30^{{}^{\circ}}}{9.8}=2 \times \frac{1}{2}=1 \mathrm\sec
