Motion in A Plane question

2022 · 27 Jun · Shift 1 · Q42

JEE MainPhysicsMotion in A PlaneMCQ+4 / −1
A projectile is launched at an angle 'α\alphaα' with the horizontal with a velocity 20 ms −-− 1. After 10 s, its inclination with horizontal is 'β\betaβ'. The value of tan β\betaβ will be : (g = 10 ms −-− 2).
  1. A
    tan α\alphaα + 5sec α\alphaα
  2. B
    tan α−\alpha-α− 5sec α\alphaα
  3. C
    2tan α−\alpha-α− 5sec α\alphaα
  4. D
    2tan α+\alpha+α+ 5sec α\alphaα
