Answer:

Explanation:  Air resistance is insignificant for heavy objects precisely because it doesn't depend on the mass. This is because a force is just an interaction that tries to change the momentum of an object, and the momentum depends on the mass; the larger the mass, the larger the momentum, and the more force you need to change it.

Answer:

t=\frac{13}{3} =4.33\ mi.hr^{-1}

Explanation:

Given:

  • Distance from the shore, s=4\ mi
  • distance of house from the shore, h=12\ mi
  • speed of rowing, v_r=3\ mi.hr^{-1}
  • speed of walking, v_w=4\ mi.hr^{-1}

<em>For the least amount of time to reach the house one must row at the nearest point on the shore and then walk from there.</em>

<u>Now the time taken to reach the shore:</u>

t_s=\frac{s}{v_s}

t_s=\frac{4}{3}\ mi.hr^{-1}

<u>Time taken in walking to house from the shore:</u>

t_h=\frac{h}{v_w}

t_h=\frac{12}{4}

t_h=\frac{12}{4}

t_h=3\ mi.hr^{-1}

<u>Therefore total time taken:</u>

t=t_h+t_s

t=\frac{13}{3} =4.33\ mi.hr^{-1}
