Sir last question me second vector kee line ke along jaate jaate jab ground se intersection le tab ek right angled triangle banta hai with angle θ, assumed angle α and the 90°. Jisse hum ye bol sakte hai that the magnitude of angles is equals the sum to 180°. Therefore, θ+α = 90°. By this, α = 90°- θ . Then the velocity at time t′, let be u′ is u′cosα = ucosθ. Therefore, u′= ucosθ/cosα. Now replace α ----> 90°- θ. Therefore, u′= ucosθ/cos(90°- θ). u'= ucosθ/sinθ = ucotθ u'= ucotθ OR u = u'tanθ Components of u'= ucotθ, The X component would be u'ₓ = ucotθcosα = u(cosθ/sinθ).cos(90°- θ) = ucosθ Therefore, u'ₓ = ucosθ (which is true) SImilarly For the Y component, u'ᵧ = ucotθ.sinα = ucotθ.sin(90°- θ) = ucos²θ/sinθ. Therefore, u'ᵧ = ucos²θ/sinθ. Let the time taken be t' u'ᵧ = uᵧ + aᵧt' -ucos²θ/sinθ -usinθ = -gt' (ucos²θ + usin²θ)/sinθ = gt' u(cos²θ + sin²θ)/gsinθ = t' Therefore, the time taken comes out to be t' = u/gsinθ Cheers!
