Question 11: When a force is applied to an object with mass equal to 1.00 kg, the acceleration of the mass is 3.25m/s2. (Assume that friction is so small that it can be ignored.) When the same magnitude force is applied to another object, the acceleration is 2.75m/s. What is the mass of this object? What would the second object's acceleration be if a force twice as large were applied to it? show your calculations.
