A body is projected horizontally from the top of a tower of height \(180 \mathrm{~m}\) with a velocity of \(20 \mathrm{~ms}^{-1}\). If acceleration due to gravity is \(10 \mathrm{~ms}^{-2}\), then match the following.
\(\begin{array}{llll}A & B & C & D\end{array}\)
- A IV II III I
- B I II III IV
- C IV II I III
- D II IV I III
Answer & Solution
Correct Answer
(C) IV II I III
Step-by-step Solution
Detailed explanation
Given, initial horizontal component of velocity, \[ u_x=20 \mathrm{~m} / \mathrm{s} \text {. } \] Initial vertical component of velocity, \[ u_y=0 \] Acceleration due to gravity, \[ g=a_y=10 \mathrm{~m} / \mathrm{s}^2 \] So, horizontal component of velocity after…
