A \(1.5 \mathrm{~kg}\) ball is shot upward at an angle of \(34^{\circ}\) to the horizontal with an initial speed of \(20 \mathrm{~m} / \mathrm{s}\), then maximum height of the ball reaches is (use \(\cos 34^{\circ}=0.83\) or \(\sin 34^{\circ}=0.56\) )
- A \(6.3 \mathrm{~m}\)
- B \(9.4 \mathrm{~m}\)
- C \(13.8 \mathrm{~m}\)
- D \(11.2 \mathrm{~m}\)
Answer & Solution
Correct Answer
(A) \(6.3 \mathrm{~m}\)
Step-by-step Solution
Detailed explanation
Given, inífial speed, \(\mathrm{u}=20 \mathrm{~m} / \mathrm{s}\) angle of projection, \(\theta=34^{\circ}\) Maximum height, \(H=\frac{\mu^2 \sin ^2 \theta}{2 g}\)…
