A certain freely falling object, released from rest, requires 1.50 s to travel the last 30.0 m before it hit the ground. a.Find

Lyrx [107]

A.)
<span>s= 30m
u = ? ( initial velocity of the object )
a = 9.81 m/s^2 ( accn of free fall )
t = 1.5 s
s = ut + 1/2 at^2
\[u = \frac{ S - 1/2 a t^2 }{ t }\]
\[u = \frac{ 30 - ( 0.5 \times 9.81 \times 1.5^2) }{ 1.5 } \]
\[u = 12.6 m/s\]
</span>
b.)
<span>s = ut + 1/2 a t^2
u = 0 ,
s = 1/2 a t^2
\[s = \frac{ 1 }{ 2 } \times a \times t ^{2}\]
\[s = \frac{ 1 }{ 2 } \times 9.81 \times \left( \frac{ 12.6 }{ 9.81 } \right)^{2}\]
\[s = 8.0917...\]
\[therfore total distance = 8.0917 + 30 = 38.0917.. = 38.1 m \] </span>

You are creating a model of a bookcase for a dollhouse.

Goshia [24]

Answer:

If the model is 3 inches tall, the model bookcase should be <em>2 inches</em> wide.

Step-by-step explanation:

When using similar figures, set up a proportion of the model measurements to the actual measurements:

$\frac{3}{48}=\frac{x}{32}$

Then cross multiply and solve for x:

$48x=96\\x=\frac{96}{48}\\x=2$

If this helped, a brainliest would be greatly appreciated!
