In a performance test, each of two cars takes 8.8 s to accelerate from rest to 26 m/s. Car A has a mass of 1442 kg, and car B has a mass of 1863 kg. Find the net average force that acts on (a) car A and (b) car B during the test.

The acceleration of the both cars is
a = 26[m/s]/8.8[s] = 65/22 [m/s²].
According to the second Newton's law, the force acting on the first car is

That's pretty simple: a = 26[m/s]/8.8[s] =26*10/88=260/88=65/22 [m/s²].
How did you get a= 26 (m/s) / 8.8 (m/s^2) = 65/22. I dont get 65/22 as the answer for it. What am I doing wrong.
