Question

A rightward force of 82.7 N is applied to a 5.03 kg object to accelerate it to the right. The friction force between the object and the surface is 27.3 N.

a) Calculate the net force.
b) Calculate the acceleration of the object.
c) Calculate the mass of the object.
d) Determine the direction of the object's motion.

Answer 1

The net force is 55.4 N, the acceleration is 11.0 m/s² to the right, and the object's motion is to the right.

Step-by-step explanation:

To calculate the net force, we need to subtract the friction force from the applied force. So, the net force is 82.7 N - 27.3 N = 55.4 N.

To calculate the acceleration, we can use Newton's second law of motion, which states that the net force is equal to the mass of an object multiplied by its acceleration (F = ma). Rearranging the equation, we get a = F/m. The mass of the object is given as 5.03 kg, and the net force is 55.4 N. Substituting these values into the equation, we find that the acceleration is 11.0 m/s².

Since the net force and acceleration are both positive values, we can determine that the direction of the object's motion is to the right.
