Question

Question 1 (1 point) Cart e Sensor In lab you will roll a cart down a nearly frictionless incline set at a small angle (see image). The cart will start at rest and travel a set distance. After travelling, the flag will pass throu photogate in order to measure the speed. f (the speed at the end of the trip). From the time measured by the photogate you calculate the final velocity to be vf- 1.84 :0.09 m/s. What is the percent uncertainty in the final velocity? Your Answer Answer units

Answer 1

Percent uncertainty in Vf = uncertainty in Vf*100/Vf

0.09*100/1.84 = 4.9 %
