Question

A cart is allowed to roll down an inclined track and its speed a the bottom of the track is measured. The measurement is repeated five times and the results are recorded in the table below. In the questions that follow, do not round your answers unless you are specifically instructed to.

Trial	Velocity (m/s)
1	0.671459
2	0.672207
3	0.669468
4	0.666862
5	0.669818
