Q.85 A body A of mass m is thrown with velocity υ at an angle 30 ∘ to the horizontal and another body B of the same mass is thrown with velocity υ at an angle of 60 ∘ to the horizontal, find the ratio of the horizontal range and maximum height of A and B. Answer: For body A : θ = 30 ∘ Horizontal range, Maximum height,
bUEStIOns: 1. How would the horizontal range change if the muzzle velocity was doubled? Explain (use the equation from the Theory part, if needed 2. How would the horizontal range change if the height from the ground was doubled? Explain. . How would the horizontal range change if the mass of the ball was doubled? Explain.
Oct 18, 2019 · This is the equation of parabola. So, the trajectory of the projectile fired parallel to the horizontal is a parabola. The velocity of the projectile at any time. Along the horizontal axis, \(a_x = 0\) so, velocity remains constant and velocity at \(A\) along horizontal will also be \(u\). Along vertical, \(u_y = 0\) \(a_y = g\) By first ...
Ex.1 A projectile fired with initial velocity u at some angle has a range R. If the initial velocity be doubled at the same angle of projection, then the range will be(A) 2R Sol. (D) R = (B) R/2 (C) R (D) 4R. u2 sin 2 g. R u2 . If initial velocity be doubled than range will become four times.
