With the given values of
, we have

Try dealing with the powers of 10 first: On the right, we have

Meanwhile, the other values on the right reduce to

Then taking units into account, we end up with the equation

Now we solve for
:


or, if taking significant digits into account,

1)
first you find the maxium force that the car can produce.
f=ma
Fmax=(1100kg)(6m/s^2)
then use f = ma again to find the accel with the passengers
Fmax=(1100kg +1650kg)(a)
=> a = (1100kg)(6m/s^2)/( 1100kg +1650kg)
= 2.4 m/s^2
I think it is either A or B. I’m mostly leaning towards B.
