Vedclass · Answer

(C) For the bullet to hit the fighter jet,the horizontal component of the bullet's velocity must be equal to the horizontal velocity of the jet so that the bullet stays directly under the jet throughout its flight.Let $v_j = 200 \; m/s$ be the speed of the jet and $v_b = 400 \; m/s$ be the speed of the bullet.The horizontal component of the bullet's velocity is given by $v_{bx} = v_b \cos 	heta$.Equating the horizontal components: $v_j = v_b \cos 	heta$.Substituting the values: $200 = 400 \cos 	heta$.Therefore,$\cos 	heta = \frac{200}{400} = 0.5$.Thus,$	heta = \cos^{-1}(0.5) = 60^\circ$.
