An object is projected with a velocity of 20 m/s making an angle of 45 0 with horizontal. The equation for the trajectory is h = Ax – Bx 2 where h is height, x is horizontal distance. A and B are constants. The ratio A: B is : (g = 10 ms –2 )
Text Solution
Verified by ExpertsThe correct answer is:
D
u = 20, θ = 45º Given h = Ax – Bx 2 comparing with y = x tan θ – 
, A = tan θ = tan 45 0 = 1
And B =
