A bullet is fired from a gun at 30\(^o\) to the horizontal. The bullet remains in flight for 25s before touching the ground. Calculating the velocity of projection. [g = 10ms\(^{-2}\)]
Calculation of velocity of fired bullet
Time of flight T = \(\frac{2u sin \theta}{g}\)
25 = \(\frac{2u sin 30}{g}\)
u = 250ms\(^{-1}\)
