A 2450 kg car traveling to the west at 16.4 m/s slows down uniformly under a force of 8930 N to the east.
a) How much force would be required to cause the same acceleration on a car of mass 3170 kg? Answer in units of N.
The Attempt at a Solution
I found in the first cart 2450x16.4 = 40,180 kg*m/s (the momentum)
Since 8930 N is the same as 8930 kg*m/s^2
40,180 / 8930 = 4.49900449 seconds
I tried to use a similar with the second cart 3170 kg, but the problem is I don't know the force since i'm trying to find it I got stuck.
