There are three different situations in which mass is doubled (40 to 80 kg, 50 to 100 kg, and 100 to 200 kg). What happens to the time to reach the final velocity each time the mass is doubled? What happens to the acceleration of the object each time the mass is doubled? 2. What is the best value and uncertainty for your calculated velocity? 3. What would it take for a 100 kg mass to have the same acceleration as a 50 kg mass, given the values you are allowed to change in the simulation?
