In a sport event a disc is thrown such that it reaches its maximum range of 80 m , the distance travelled in first 3 s is \(\left(\mathrm{g}=10 \mathrm{~ms}^{-2}\right)\)
- A 80 m
- B 60 m
- C 72 m
- D 74 m
Answer & Solution
Correct Answer
(B) 60 m
Step-by-step Solution
Detailed explanation
\(\mathrm{R}_{\max }=\frac{\mathrm{u}^2}{\mathrm{~g}}=80 \Rightarrow \mathrm{u}=\sqrt{800} \mathrm{~m} / \mathrm{s}\) \(x=(u \cos \theta) t=\left(u \cos 45^{\circ}\right) \times=\frac{3}{\sqrt{2}} \times \sqrt{800}=60 m\)
