Final answer:
To find the mass of the object, which experiences a net force of 250 N and accelerates at 13 m/s squared, we use Newton's second law formula m = F/a. Plugging in the values, we calculate the mass to be 19.23 kg.
Step-by-step explanation:
The student asks about the mass of an object that accelerates when a net force is applied. This is a classic physics problem involving Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object times its acceleration (F = ma).
To find the mass of the object (m), we use the formula m = F/a, where F is the net force applied to the object and a is the acceleration of the object. Given that the net force (F) is 250 N and the acceleration (a) is 13 m/s2, the mass (m) can be calculated as follows:
m = F/a = 250 N / 13 m/s2 = 19.23 kg (rounded to two decimal places).
Therefore, the mass of the object is 19.23 kg.
