convert 6 days to seconds  (6days)x(24hrs/1day)x(3600s/1hr)= 518,400s 
A physics teacher drops a ball from a height, the students below time how long it takes the ball to fall, they have the following times. Student 1: 4.48s student 2: 4.85s Student3: 5.06s Student 4: 5.12s what is the absolute error taken by student 4?  Using Ea=I Maverage of MI Average of M=(4.48s+4.85s+5.06s+5.12s)/4 average of M=4.88s 5.12s4.88s= .24s 
What is the relative error student 4?  Er=(Ea/average of M) x100% Er=(.24s/4.88s)x100% Er=4.9%
