To find the acceleration of the trailer, we can use Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. The formula for acceleration is: **a = F/m** Where: - **a** is the acceleration - **F** is the net force acting on the object - **m** is the mass of the object In this case, the net force acting on the trailer is the tractive force provided by the tractor, and the mass of the trailer is not given. However, we can assume that the mass of the trailer is negligible compared to the force applied. Given: - Tractive force provided by the tractor (F) = 60 kN - Acceleration of the trailer (a) = 0.5 m/s^2 We can rearrange the formula to solve for the mass of the trailer: **m = F/a** Substituting the given values: **m = 60 kN / 0.5 m/s^2** Converting the tractive force from kilonewtons (kN) to newtons (N): **m = 60,000 N / 0.5 m/s^2** Simplifying: **m = 120,000 kg** Now that we have the mass of the trailer, we can calculate the acceleration using the formula: **a = F/m** Substituting the given values: **a = 60 kN / 120,000 kg** Converting the tractive force from kilonewtons (kN) to newtons (N): **a = 60,000 N / 120,000 kg** Simplifying: **a = 0.5 m/s^2** Therefore, the acceleration of the trailer will be **0.5 m/s^2** when the tractive force provided by the tractor is 60 kN. Please note that the calculations assume that the mass of the trailer is negligible compared to the force applied by the tractor.
