STANDARD Physics Angle of Projection MCQ Question
The equations of motion of a projectile are given by x = 36t m and 2y = 96t − 9.8 t² m. The angle of projection is
sin⁻¹(4/5)
sin⁻¹(3/5)
sin⁻¹(4/3)
sin⁻¹(3/4)
Correct Answer
Detailed Explanation
The initial horizontal and vertical components of velocity are found using the derivatives of x and y with respect to time. The ratio of these components gives tanθ = 48/36 = 4/3. Using trigonometric identities, θ = sin⁻¹(4/5).
