You are standing on a sheet of ice that covers the football stadium parking lot in Buffalo; there is
Arlecino [84]

Answer:

a) v=0.5405\ m.s^{-1}

b) v_p'=0.1143\ m.s^{-1}

Explanation:

Given:

mass of ball, m_b=4\ kg

initial speed of the ball, v_b=10\ m.s^{-1}

mass of the person, m_p=70\ kg

a)

Using the conservation of linear momentum:

When the person catches the ball, assuming that the person catches it with an impact without absorbing the shock.

m_b.v_b=(m_b+m_p)v

4\times 10=(4+70)\times  v

v=0.5405\ m.s^{-1}

b)

When the ball hits the person and bounces off with the velocity of v_b'=8\ m.s^{-1}.

Using the conservation of linear momentum:

m_b.v_b+m_p.v_p=m_b.v_b'+m_p.v_p'

where:

v_b'= final speed of the ball after collision

v_p'= final speed of the person after collision

v_p= initial velocity of the person = 0

putting the respective values in the above eq.

4\times 10+0=4\times 8+70\times v_p'

v_p'=0.1143\ m.s^{-1}

When you exert 75 N on a jack to lift a 6000 N car, what is the jack’s actual mechanical advantage? Show your work.
professor190 [17]

Answer:

80

Explanation:

<em>the </em><em>mechanical</em><em> </em><em>advantage</em><em> </em><em>is </em><em>the </em><em>ratio </em><em>of </em><em>the </em><em>load </em><em>to </em><em>the </em><em>effort</em><em> </em><em>so </em><em>it </em><em>doesn't</em><em> </em><em>have </em><em>units.</em><em>t</em><em>o</em><em> </em><em>calculate</em><em> </em><em>it </em><em>you </em><em>use </em><em>the </em><em>formula</em>

<em>mechanical</em><em> advantage</em><em>=</em><em>load/</em><em>effort</em>

<em>in </em><em>this</em><em> case</em><em> </em><em>the </em><em>load </em><em>is </em><em>6</em><em>0</em><em>0</em><em>0</em><em>N</em><em> </em><em>and </em><em>the </em><em>effort</em><em> </em><em>is </em><em>7</em><em>5</em><em>N</em>

<em>Ma=</em><em>6</em><em>0</em><em>0</em><em>0</em><em>/</em><em>7</em><em>5</em>

<em>=</em><em>8</em><em>0</em>

<em>I </em><em>hope</em><em> this</em><em> helps</em>
