Makya was conducting a physics experiment. he rolled a ball down a ramp and calculated the distance covered by the ball at different times. the ball rolled a distance of 1 foot during the first second, 3 feet during the next second, and so on. if the distances the ball rolled down the ramp each second form an arithmetic sequence, determine the distance the ball rolled down during the fifteenth second.

Makya was conducting a physics experiment. At 15th second, distance rolled will be 29 feet.

Solution:

Given that Makya is conducting physics experiments.

He rolled a ball down a ramp and calculated the distance covered by the ball at different time.

Ball rolled a distance of 1 foot during first second.

Ball rolled a distance of 3 feet during second second.

Given that distance rolled with the time formed an arithmetic sequence.

We need to calculate distance rolled at 15th second that is 15th term of Arithmetic sequence when,

Hence at 15th second, distance rolled will be 29 feet.

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.
