Ok so the formula is d=vi(t)+½at² and when you substitute it you should get 172.5meters
Answer:
friction can be used to slow things down but it can also be harmful because it can cause fire to start
Answer and Explanation
Arranging the measured values in increasing order;
4.3s, 4.6s, 4.6s, 4.8s, 5.1s, 5.8s
The two outliers are obviously 4.3s and 5.8s; An outlier is a value in a statistical sample which does not fit a pattern that describes most other data point. Outliers make the average value complicated. So, it is usually better for data to be precise with data points spreading out around a small area.
So, the mean is the average of the four remaining data points after removing the outliers.
Mean = (4.6 + 4.6 + 4.8 + 5.1)/4
Mean = 4.775s
So, the value recorded should be 4.775s, 4.78s or 4.8s depending on the number of decimal places allowed.
QED!
Density is directly proportional to mass. So if there's less matter inside object, its density will also reduce.
Hotter ocean tempatures mean more moisture in the dense air mass
