Questions
The path followed by a body projected along y-axis is given as by if g = 10 m/s2, then the initial velocity of projectile is (x and y are in m)
detailed solution
Correct option is B
On comparing the coefficient of x2 in the given equation with the standard equation, we gety=x tan θ−gx22u2cos2θ tanθ=3,θ=600 ⇒g2u2cos2θ=12Substituting θ = 60°, we get u=210 m/s.Talk to our academic expert!
