Question

In lab you will roll a cart down a nearly frictionless incline set at a small angle. The cart will start at rest and travel a distance of 30.0cm±0.2cm. After travelling, the flag will pass through the photogate in order to measure the speed, vf or v30 (the speed at the end of the 30.0cm trip).

Size of flag: d(flag width)=1.50cm±0.10cm

Time through photogate t(blocked) = 0.02095s±0.00010s

1. What is the final speed of the cart? (after traveling 30 cm)

2. Find the percent error of the final velocity (%v30):

3. Find the absolute error of the final velocity (v30):

Provide final answer in the following format:

v30=__________m/s±__________%

v30=__________±__________m/s
