AP EAMCET · PHYSICS · Motion In Two Dimensions
A body is projected at an angle other than \(90^{\circ}\) with the horizontal with same velocity. If the time of ascent of the body is ls, then the maximum height it can reach is (Take, \(g=10 \mathrm{~ms}^{-2}\) )
- A 5 m
- B 10 m
- C 2.5 m
- D 75 m
Answer & Solution
Correct Answer
(A) 5 m
Step-by-step Solution
Detailed explanation
Given, angle of projection, \(\theta=90^{\circ}\) and time of ascent, \(t=1\) s. Since, time of ascent of a projectile body is half of the time of height, \(T=2 \times 1=2 \mathrm{~s}\) Equation of motion, \[ \mathrm{s}=u t+\frac{1}{2} g t^2 \] where, \(s=0\) for complete…
