A little car of mass M1 has a maximum acceleration of 2.57m/s^2 when applying a force F1. What is the new maximum acceleration of the little car if it tows another car that has the same mass M1 and the same applied force F1?

For little car without towing,
F1 = M1*2.57.........................(1)
When towing another car of same mass M1, with same force F1:
F1 = (M1 + M1)*a
F1 = 2M1*a
a = F1/2M1
from eqn (1) put the value we get,
a = 2.57M1/2M1 => 2.57/2 => 1.285 m/s^2
