<p>Dotted Arrow —&gt;</p><p>(and its forumla)</p>

Dotted Arrow —>

(and its forumla)

Fpx = Fpcosθ

2
New cards
<p>Dotted Arrow ^</p><p>(and its formula)</p>

Dotted Arrow ^

(and its formula)

Fpy = Fpsinθ

3
New cards
<p>Bold Arrow v</p>

Bold Arrow v

W = mg

4
New cards
<p>To find Fn</p>

To find Fn

(simga)Fy = Fn + Fpy - W = 0

Fn = W - Fpy

mg-Fpsin0

<p>(simga)Fy = Fn + Fpy - W = 0</p><p>Fn = W - Fpy</p><p> mg-Fpsin0</p>
5
New cards
<p>For ax</p>

For ax

(sigma)Fy = (Fpx - Ffr)/m = ax

<p>(sigma)Fy = (Fpx - Ffr)/m = ax</p>

<p>&lt; + v (straight down from block’s plane)</p>

< + v (straight down from block’s plane)

mgcos0

9
New cards
<p>for ax</p>

for ax

(sigma)Fx = mgsin0 - Ffr = m ax

mgsin0 - uk*Fn[or mgcos0]

gsin0 - uk*gcos0 = ax

<p>(sigma)Fx = mgsin0 - Ffr = m ax</p><p>mgsin0 - uk*Fn[or mgcos0]</p><p>gsin0 - uk*gcos0 = ax</p>
10
New cards
<p>for v (given)</p>

for v (given)

v² = vo² + 2ax*(delta)x

<p>v² = vo² + 2ax*(delta)x</p>
