You have to find the final velocity first so you use the formula \(v=v_0+at\). \(v=15m/s+3.5m/s^2(5.0s)\\ v=15m/s+17.5m/s \\ v=32.5m/s\) Then you use the formula \(v^2=v_0~^2+2a(x-x_0)\) (\(32.5m/s)^2=(15m/s)^2+2(3.5m/s^2)(x)\\ 1056.25m^2/s^2=225m^2/s^2+7sec(x)\\ 831.25m^2/s^2=7sec(x)\\ x=118.75m\) so I rounded to 120m.

A car has a velocity of 15 m/s. It then accelerates at a uniform rate of 3.5 m/s^2 for the next 5.0 seconds. What distance does the car cover during this time?

that is the right problem.. I looked at the one above it that had 190 lol XD thanks @Shalante for pointing that out
