You are given a linear motion problem that gives you an object’s acceleration and a number in kilograms for the object’s mass. What are you solving for? (HINT: Remember your formulas)
none of the above
You are given a problem studying the acceleration of car. You know the car’s total acceleration, the car’s top velocity, and that the car started from rest. What are you solving for? (HINT: Remember your formulas!)
