Physics QUESTION #7324

Question 3887

A particle is projected vertically upward with $u = 10\text{ m/s}$. Air exerts a resistive force $F = -0.2v^2$ on it ($m = 2\text{ kg}$, $g = 10\text{ m/s}^2$). The maximum height attained is:

$5\ln 2$✔️
$3\ln 2$
$2\ln 2$
$10\ln 2$

Correct Answer Logic:

Net force (taking up as positive): $F_{net} = -mg - 0.2v^2 = -20 - 0.2v^2$

Using $ma = v\dfrac{dv}{dx}$: $2v\dfrac{dv}{dx} = -20 - 0.2v^2$

Separating variables: $\dfrac{v\,dv}{20+0.2v^2} = -\dfrac{dx}{2}$

Integrating from $v = 10$ to $v = 0$: let $k = 20 + 0.2v^2$, $dk = 0.4v\,dv$

$\dfrac{1}{0.4}\big[\ln(20) - \ln(40)\big] = -\dfrac{H}{2} \Rightarrow H = \dfrac{2\ln 2}{0.4} = \mathbf{5\ln 2}$

Mathematics QUESTION #7447

Question 3892

If the 2nd, 5th and 9th terms of a non-constant A.P. are in G.P., then the common ratio of this G.P. is:

$\frac{4}{3}$✔️
1
$\frac{7}{4}$
$\frac{8}{5}$

Correct Answer Logic:

Let the A.P. be $a, a+d, a+2d, \ldots$ The 2nd term is $a+d$, 5th term is $a+4d$, and 9th term is $a+8d$. For these to be in G.P.: $(a+4d)^2 = (a+d)(a+8d)$. Expanding: $a^2 + 8ad + 16d^2 = a^2 + 9ad + 8d^2$, which simplifies to $8d^2 = ad$. Since the A.P. is non-constant, $d \neq 0$, so $a = 8d$. The three terms become $9d, 12d, 16d$. Common ratio = $\frac{12d}{9d} = \frac{4}{3}$.
