Answer: To determine the acceleration of an object in response to a net force, you can use the equation a = F/m, where a is the acceleration, F is the net force, and m is the mass of the object. In your case, the net force is 2.5 N and the mass of the object is 16.2 g. Since the units of force are in newtons and the units of mass are in grams, you will need to convert the mass to kilograms before plugging the values into the equation.
One kilogram is equal to 1000 grams, so 16.2 grams is equal to 0.0162 kilograms. Plugging this value into the equation, we get:
a = F/m
a = 2.5 N / 0.0162 kg
a = 154.32 m/s^2
Thus, the acceleration of the object in response to the net force of 2.5 N is 154.32 m/s^2.
