A particle is thrown upward with a speed u at an angle θ with the horizontal. When the particle makes an angle φ with the horizontal, its speed changes to v, then
- \(v=u \cos \theta \cos \phi\)
- \(\mathrm{v}=\mathrm{u} \cos \theta \sec \phi\)
- \(v=\pi \cos \theta\)
- v = u sec cos
Answer
(B) v = u
