In lab, you propel a cart with four known forces while using an ultrasonic motion detector...
The mass of the cart is 0.365 kg. The rest of the data can be obtained from the graph above. All answers below must be correct to 3 significant figures. Units are required if not stated. What the final speed of the cart predicted by the work done by the rubber band, assuming that friction negligible? Vpred What the percent difference between between the predicted and measured final speed, expressed as a percent of the measured speed? Percent difference between...
