Artemon [7]

Complete Question

A 75 kg man and a 100. Kg woman are playing tug of war on a frictionless surface. The man accelerates toward the woman at 2.0 m/s2.How much force does she use to pull on the rope

Answer:

The value is  F  =  150 \  N

Explanation:

From the question we are told that

    The mass of the man is  m_m   =  75 \  kg

     The mass of the woman is  m_f  =  100 \  kg

     The acceleration of the man is  a_m  =  2.0 \  m/s ^2

Generally the force which she used to pull the rope is mathematically represented as  

           F  =  m  *  a

=>         F  =  75 *  2

=>         F  =  150 \  N
