Answer:-

✰ Required Diagram ✰

$\setlength{\unitlength}{1mm}\begin{picture}(8,2)\thicklines\multiput(9,1.5)(1,0){50}{\line(1,2){2}}\multiput(33,7)(0,4){12}{\line(0,1){2}}\multiput(36,10)(0,4){12}{\line(0,1){2}}\put(10.5,6){\line(3,0){50}}\put(34,60){\circle*{10}}\put(8,8){\large\sf{u = 29.4 m/s}}\put(37,55){\large\sf{v = 0 m/s}}\put(22,61){\large\textsf{\textbf{Ball}}}\put(36,12){\vector(0, - 4){5}}\put(33,50){\vector(0,4){5}}\end{picture}$

Initial Velocity ( u ) = 29.4 m/s

Final Velocity ( v ) = 0 m/s [ As Ball will be at rest after attending maximum height ]

Acceleration due to Gravity = - 9.8 m/s²

⠀

$\underline{\bigstar\:\textsf{Using First Motion under Gravity :}}$

$:\implies\sf v = u + gt\\\\\\:\implies\sf 0=29.4\:m/s+(-\:9.8\:m/s^2) \times t\\\\\\:\implies\sf - \:29.4\:m/s = -\:9.8\:m/s^2 \times t\\\\\\:\implies\sf \dfrac{ - \:29.4\:m/s}{-\:9.8\:m/s^2} = t\\\\\\:\implies\underline{\boxed{\sf t = 3 \:seconds}}$

$\rule{180}{1.5}$

$\underline{\bigstar\:\textsf{According to the given Question :}}$

As no external forces are acting on Ball, Hence

$\dashrightarrow\textsf{Time of ascent = Time of decent}\\\\\\\dashrightarrow\sf Total\:Time=Time \:of \:ascent+Time \:of\:decent\\\\\\\dashrightarrow\sf Total\:Time=Time \:of \:ascent + Time \:of \:ascent\\\\\\\dashrightarrow\sf Total\:Time=3 \:seconds + 3 \:seconds\\\\\\\dashrightarrow \underline{ \boxed{\sf Total\:Time=6\:seconds}}$

⠀

$\therefore\:\underline{\textsf{Ball will return to players hand after \textbf{6 seconds}}}.$

Answer 2

$\huge{\underline{\boxed{\tt{Answer:}}}}$

Lord Ullifr’s beautiful daughter loves the Scottish chieftain passionately. Her father Lord Ullin is against their relationship and marriage. He is not favourably disposed to the Scottish chieftain. So Ullin’s daughter defies her father and decides to elope with her lover. She does so to escape the wrath of her angry father.It is only a speculation. Perhaps she heard her father giving assurance of forgiving them. That would have prompted the daughter stretching her hand for aid in those circumstances. Otherwise, she would have preferred facing the stormy sea and scowling sky to an angry father.
