<h3>✒️ACCELERATION</h3>

=================================

$\large\sf\underline{Problem:}$

Calculate the acceleration of riding her bicycle in a straight line that speeds up from 4 m/s to 12 m/s in 10 seconds.

=================================

$\large\sf\underline{Answer:}$

$\qquad \qquad \huge \rm = 0.8 \: m/s²$

=================================

$\large\sf\underline{Solution:}$

Here we have a given of,

$\tt{(12\:m/s) \:= \:V_f = (final\: velocity) }$
$\tt{(4\:m/s)\:=\:V_i = (initial \: velocity) }$
$\tt{(10\:sec) \:=\:T = (elapsed time) }$

$\bold{Formula\:||\: Acceleration = \frac{v\: - \:v_0}{t} = \frac{ΔV}{ΔT} }$

Because acceleration has a direction <u>(</u><u>riding her bicycle in a straight line</u><u>)</u>, it is important to always subtract the final velocity represented as $\bold{V_f}$ from your initial velocity also represented as $\bold{V_i}$ .

Now 'Work it out' and solve for Acceleration of riding her bicycle using the given formula.

$\large\rm{A = \frac{V_f \:- \:V_i}{T} }$
$\large\rm{A = \frac{(12\:m/s\:-\:4\:m/s) }{10\:sec}}$
$\large\rm{A = \frac{ 8\:m/s}{10\:sec} }$
$\large\rm{A = 0.8\:m/s²}$

Hence, The total acceleration of the girl riding her bicycle is 0.8 meters per second squared (m/s²).

Describe how you would use the distributive property to simplify {39×5}

GuDViN [60]

Have you learnt about prime numbers yet? 5 is a prime number so you can't break it up into smaller numbers other than obviously 5*1. 39 is not a prime number. At first glance you should be able to tell that its a multiple of 3 right?
39=3*13

Now you have smaller numbers.

3*13*5=13*15.

I guess that's what the answer is.

Firlakuza [10]

Answer:

2/8

Step-by-step explanation:

freshman=4/8

1/8 soph 1/8 jr

add all together u get 6/8

the rest is seniors so its 2/8
