The Correct Option is D

Solution and Explanation

The maximum vertical height is related to the maximum velocity as: \[ H_{\text{max}} = \frac{v^2}{2g} \] Given \(H_{\text{max}} = 136 \, \text{m}\), solve for \(v^2\): \[ v^2 = 2g H_{\text{max}} = 2 \cdot 9.8 \cdot 136 = 2 \cdot 136 \, \text{(using \(g \approx 9.8 \, \text{m/s}^2\))}. \] The maximum horizontal range \(R_{\text{max}}\) is given by: \[ R_{\text{max}} = \frac{v^2}{g} = 2H_{\text{max}} = 2 \cdot 136 = 272 \, \text{m}. \]

Concepts Used:

Motion in a Plane

It is a vector quantity. A vector quantity is a quantity having both magnitude and direction. Speed is a scalar quantity and it is a quantity having a magnitude only. Motion in a plane is also known as motion in two dimensions. 

Equations of Plane Motion

The equations of motion in a straight line are:

v=u+at

s=ut+½ at2

v2-u2=2as

Where,

  • v = final velocity of the particle
  • u = initial velocity of the particle
  • s = displacement of the particle
  • a = acceleration of the particle
  • t = the time interval in which the particle is in consideration
