Question

A particle is thrown with a speed u at an angle q to the horizontal. When the particle makes an angle f with the horizontal, its speed changes to v –

• A. v = u cosq
• B. v = u cosq. cosf
• C. v = u cosq. secf
• D. v = u sec q. cosf

Answer 1

Answer: (C)

v = u cosq. secf

Answer 2

v cosf = u cosq
