Answer:

The answer is "6\  \frac{m}{s}"

Explanation:

The formula for velocity:

\to \overline{v}={\frac{\Delta x}{\Delta t}}

      =\frac{6}{1}\\\\=6\  \frac{m}{s}

You are a detective investigating why someone was hit on the head by a falling flowerpot. One piece of evidence is a smartphone
umka21 [38]

Answer:

0.37 m

Explanation:

Given :

Window height, h_1 = 1.27 m

The flowerpot falls 0.84 m off the window height, i.e.

h_2 = (1.27 x 0.84 ) m in a time span of $t=\frac{8}{30}$   seconds.

Assuming that the speed of the pot just above the window is v then,

h_2=ut+\frac{1}{2}gt^2

$(1.27 \times 0.84) = v \times \left( \frac{8}{30} \right) + \frac{1}{2} \times 9.81 \times \left( \frac{8}{30} \right)^2$

$v=\left(\frac{30}{8}\right) \left[ (1.27 \times 0.84) - \left( \frac{1}{2} \times 9.81 \times \left( \frac{8}{30 \right)^2 \right) \right]}$

$v= 2.69$ m/s

Initially the pot was dropped from rest. So,  u = 0.

If it has fallen from a height of h above the window then,

$h = \frac{v^2}{2g}$

$h = \frac{(2.69)^2}{2 \times 9.81}$

h = 0.37 m
