A car starts from rest and begins moving on a road. It encounters 1000 N of air resistance and 11,000 N of applied force from floor to the tires on the car. During this motion, the car is accelerating at a rate of 5.5 m/s^2. What is the car’s mass? How fast is the car going 10s later? How far did it travel in this time period? Draw the x-t graph and v-t graph for this motion and system schema and FBD! Please please
