AP EAPCET 2024 - 23th May Morning Shift | Motion in a Straight Line Question 1 | Physics

A diving board is at at height of $h$ from the water surface. A swimmer standing on this board thrown a stone vertically upward with a velocity $16 \mathrm{~ms}^{-1}$. It reaches the water surface in a time of 5 s . In the next 0.2 s the diver can hear the sound from water surface. The speed of sound is (acceleration due to gravity $g=10 \mathrm{~ms}^{-2}$ )

$450 \mathrm{~ms}^{-1}$

$225 \mathrm{~ms}^{-1}$

$200 \mathrm{~ms}^{-1}$

$275 \mathrm{~ms}^{-1}$

A particle starts from rest and moves in a straight line. It travels a distance $2 L$ with uniform acceleration and then moves with a constant velocity a further distance of $L$. Finally, it comes to rest after moving a distance of $3 L$ under uniform retardation. Then, the ratio of average speed to the maximum speed $\left(\frac{v}{v_m}\right)$ of the particle is

$\frac{6}{11}$

$\frac{7}{11}$

$\frac{5}{11}$

$\frac{2}{11}$

The velocity of a particle is given by the equation $v(x)=3 x^2-4 x$, where $x$ is the distance covered by the particle. The expression for its acceleration is

$(6 x-4)$

$6\left(3 x^2-4 x\right)$

$\left(3 x^2-4 x\right)(6 x-4)$

$(6 x-4)^2$
