Record the mass with 3 added weights here (mcart = 0.250 kg) MTotal =2. Zero the sensors and change the data collection from manual to periodic (50 Hz).3. Start the data collection and pull the cart 3 - 5 cm down the incline (Do not over stretch, bad things will happen to your grade), and release the cart. It should oscillate back and forth. Collect data for a few cycles and stop the data collection.1. Select the velocity measurement. Select a nice peak and measure the max value (click the summation sign when you select the data)2. Calculate the kinetic energy of the cart here: KE = Mv? =3. Where is the cart (max height, min height, or equilibrium position) when you measure the peak kinetic energy? Explain your answer in terms of energy, use your graph of force for evidence.4. Select Force on your run data list. Measure the next peak that occurs for force from the one you measure with velocity. Find the max force here.5. Use your spring constant, k, to calculate the max stretch of the spring from equilibrium
