Question

The path followed by a body projected along y axis is given as by y = √3 X – (1/2) x².If g = 10 m/s² then the initial velocity of projectile will be- (x and y are in m)

(1) 3 √10 m/s

(2) 2 √10 m/s

(3) 3 √3 m/s

(4) 10 √2 m/s

Answer 1

Correct Answer is: (2) 2 √10 m/s

Given, that y = √3 x – (1/2) x² ...(A)

The above equation is similar to equation of trajectory of the projectiles
