Ben walks 500 meters from his house to the corner store. He then walks back toward his house but stops to talk to a neighbor whe

Black_prince [1.1K]

Answer:0.33 m/s

Explanation:

Given

Ben walks towards corner stone which 500 m from his house

As he walk back he stop to talk his neighbor which is 200 m from corner stone

Average velocity of Ben is given by the ratio of his displacement and total time taken

Displacement of Ben is $=500-200=300\ m$

total time taken by Ben $=910\ s$

$v_{avg}=\frac{displacement}{time}$

$v_{avg}=\frac{300}{910}$

$v_{avg}=0.33\ m/s$

A lumberjack (mass = 103 kg) is standing at rest on one end of a floating log (mass = 277 kg) that is also at rest. The lumberja

Lorico [155]

Answer:

Explanation:

Given

mass of lumber jack $m_L=1000 kg$

mass of floating log $m_f=277 kg$

velocity of lumber jack =3.74 m/s (w.r.t. shore)

conserving momentum

Initial momentum=Final momentum

$0=m_L\times 3.74+m_f\times v$

$v=-\frac{1000\times 3.74}{277}$

$v=-13.501 m/s$

(b)For second Log

Conserving Momentum

Initial momentum of log and Lumber jack=Final momentum of log and lumberjack

$m_L\times 3.74=(m_L+m_f)u$

u is final velocity of lumberjack and log

$u=\frac{m_L}{m_L+m_f}\times 3.74$

$u=\frac{1000}{1000+277}=2.92 m/s$
