What is the inertial mass of a bus that accelerates at a rate of 0.5m/s/s when 5 people push it, each with a force of 750N.

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

your answer is c! hope this : )
