Question

Setup 1. For Run #1 use the arrangement described above (one 20-g mass on the mass hanger, weigh the cart and the mass hanger with a 20-g mass, and enter these values in Table 1 2. Pull the cart about 25 cm from the endstop. Click Start. Release the cart Stop the cart before it hits the pulley and click Stop 3. For Run #2 add a 250-g mass to the cart Weigh the total mass of the cart plus the extra mass and record this value in Table 1 4. For Run #3. add a second 250-g mass to the cart Weigh the total mass ofthe cart plus the two extra masses and record this value in Table 1. Table 1 Mass (kg) 0.479 0.028 0.769 1.016 Item Run #1 : Mass of the cart Run #1 : Total mass of the hanger and 20-q mass Run #2: Total mass of cart plus one 250-g mass Run #3: Total mass of cart plus two 250-g masses! Calculations 1. The acceleration is the ratio of the net force divided by the total mass. Calculate the net force, net, and record it below Ft net 2. Calculate the theoretical acceleration, ah, when the net force is constant and the mass is changed and record the calculations in Table 2 Ticart + mhanger imasses or runs #1, #2, #3, the total mass of the system, mto (the total mass of the cart, hanger, and any other masses or weights) increases and the net force ((mass of hanger-20-g mass)-9.8) remains consta 3. Find the percent error betveen the theoretical and experimental acceleration and record it in Table 2.
