Question

13. A bail is projected at an angle 0 - tan(2) with respect to horizontal. The angle made by the position vector of ball with honizontal when ball reaches at the topmost point of projectile is​

Answer 1

Answer:

Correct option is D)

Horizontal velocity of projectile after time t =vcosθ

Vertical velocity of projectile after time t=vsinθ−gt

Angle at any time t:

tanϕ=

v

h

v

v

=

vcosθ

vsinθ−gt

ϕ=tan

−1

vcosθ

vsinθ−gt
