A cаrt оf mаss 210g is cоnnected оver а pulley to a hanging mass mh. Thesystem is released from rest and acceleration is measured using a motion sensor. Data for five trials is shown below. Trial Hanging Mass (kg) Measured Acceleration (m/s²) 1 0.020 0.83 2 0.030 1.19 3 0.040 1.54 4 0.050 1.86 5 0.060 2.14 Answer the following questions individually. Please number your responses to match the question number.1. If you plotted acceleration vs. applied force, would you expect a linear relationship? Explain. 2. If a small friction force existed, would it make the measured slope larger or smaller thanexpected? Explain. 3. Compare the calculated mass to the actual total mass (Mcart + Mhanging) is the calculated mass larger or smaller? Give one reason why the calculated mass may be different from the total mass.
