Question

A projectile is given an initial velocity of i ^ + 2 j ^ 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 :, 4 y = 2 x - 5 x 2, 4 y = 2 x - 25 x 2, y = x - 5 x 2, y = 2 x - 5 x 2

MARKS App · Accepted Answer

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
