Question

The distance - time graph of a particle in a projectile motion is a curse parabols. Whaboo

projected from the ground, it reaches a certain height and comes back to the The path

it followed is a parabola and parabolas are symmetrie. The general option of a parabola ay

M

x (Quadratic polynomial)

If the projected parabolie path is represented by the equation yst- 71 +12 then what we them

a) (-1.5)

14,3)

b) If the body is in ground level at t = 4 sec and t = 7 sec, then the representation of the projectile

a) -- 5t3 b)r - 141 +11

- Ilt+28

ii) The representation of the projectile whose one root is-5 and the other root is ismeciprocal is

a) + 25

b) - 25

c)r + √ d-

iv) Consider the projectile is represented as F-9+20. If the body is projected 2 secl than the

to time and reaches the ground 2 sec later than the actual time. The representaion of the projectile

a)-156 + 30 b) - 18t+42 c)+181-42 )-2

v) If one of the root of the projectile is 2+ 3. then the other is
