Question

Select "Acceleration" in the Forces and Motion: Basics HTML5 simulation. You should see a mannequin-like figure standing next to an object. Check the "Force", "Sum of Forces", "Values", "Masses", "Speed", and "Acceleration" boxes. Move the Friction slider all the way over to the right so that there's Lots of friction. Apply a force of 500 N on the girl. Repeat that with the man. From what you observe,

the acceleration of the _______ (man or girl) is larger because the net force is a. larger on the girl B. larger on the man C. the same on both the girl and the man while the mass is a. the same for the both the girl and the man b. smaller on the man c. smaller on the girl

Answer 1

Answer::

Force applied =5000 N

Mass of girl =m_g

Mass of man=m_m

as  m_m  <  m_g

and a_m=f/m_m

a_g=f/m_g

a_m/ a_{g =}m_{g /} m_m < 1

so a_m<  a_g

acceleration of man   < acceleration of girl
