Estimate the percent uncertainty in the measurement. Rerce Osma Lab Hommeuork Lab 1: Force and Motion I Page 6 of 6 3 Cm Using the instruments from problem 1, you take the following measurements for the distance a toy car travels in 10 seconds during each of 5 trials: 157 cm, 175 cm, 162 cm, 168 cm, 187 cm. What are the percent uncertainties ol tne distance and time measurements? Which of the two measurements is the most uncertain? 3. Calculate the average speed of the toy car. Use the weakest link rule to determine the uncertainty in the speed. 4.
