To calculate the acceleration, we can use Newton's second law of motion, which states that the acceleration of an object is equal to the net force acting on it divided by its mass. In this case, the net force acting on the skater is 155 N west (in the negative x-direction) and the mass of the skater is 65 kg.
Using the formula: acceleration = net force / mass
Substituting the given values, we get:
Acceleration = -155 N / 65 kg
Calculating the result, the acceleration is approximately -2.38 m/s² in the westward direction. Note that the negative sign indicates that the acceleration is in the opposite direction of the force, as per the convention of considering positive directions.
