1) 1.08 m/s^2
Explanation:
Acceleration is equal to the change in velocity divided by the time taken:
where
v is the final velocity
u is the initial velocity
is the time taken
In this problem, we have:
- initial velocity: u = 0 (you start from rest)
- final velocity: v = 5.4 m/s
- time taken: 
Therefore, the acceleration is
2) -0.54 m/s^2
We can calculate the acceleration to slow down using the same formula as before, but this time the data are as follows:
- initial velocity : u = 5.4 m/s
- final velocity : v = 0 (you come to a stop)
- time taken : 
using the same formula, we find
And the negative sign means it is a deceleration.
<h2>
If two sets of data are correlated, this means that: one set causes the other to happen.
</h2>
Explanation:
Correlation indicates a relationship between two or more variables, but this relationship does not suggest cause and effect. When two sets of data are correlated, it means that as one variable changes, the other variable also changes.
The correlation can be measured by calculating a statistic called as correlation coefficient. The number from -1 to +1 indicates the strength and direction of the relationship between variables. The correlation coefficient is denoted by the letter r.
Answer:
A basketball sitting still in a players hands
Explanation:
The other 3 answers have the ball <u>in motion</u> (going towards the basket, bouncing, and rolling) so that would be <u>kinetic energy</u>.
When the basketball is sitting in the player's hands, it has the potential to be in motion.
