Question

Answer question number of a-d on the basis of your understanding of the following paragraph and the related studies Concepts: A projectile is projected from a point o on the ground with an initial velocite u at the an Elevation angle theta from the horizontal direction as shown in the figure it just crosses two walls A and B of same height it situated symmetrically at time t1 -2s and t2 =6s respectively. The horizontal distance between the two wall is d = 120m. you may presume g-10m/s
(1) the total time of flight of the projectile is (I)8s (ii) 10s (iii) 4s (iv)12s
(2) The value of angle of projection theta of the projectile is
(I) tan-¹(3/4) (ii) tan-¹(4/5) (iii) tan-¹(4/3) (iv) tan -¹(5/4)

(3) The projection velocity u of the projectile is
(I) 30 m/s (ii) 40 m/s (iii)50 m/s (iv) 2✓3 m/s
(4) The height h of either of two walls is
(I) 120 m (ii) 30 m (iii) 15m (iv) 60 m ​
