JEE Main 2013 — Motion In Two Dimensions Question with Solution

JEE Main 2013 (07 Apr)

Question

A projectile is given an initial velocity of i^+2j^ m s-1, where i ^ is along the ground and j ^ is along the vertical upward. If g=10 m s-2, the equation of its trajectory is :

Choose an option

Show full solutionCorrect option: D
Correct answer
Dy=2x-5x2

Step-by-step explanation

v → = i ^ + 2 j ^

⇒ x = t    ..... (i)

y = 2 t - 1 2 1 0 t 2    ..... (ii)

From (i) and (ii)

y = 2 x - 5 x 2
