Answer:

Mean =22.1

The sample proportion of numbers less than the mean is = (7/15 ) *100 =46.67%

Explanation:

Mean of the data set can be calculated by adding all numbers and dividing it with total number sample data.

Adding all the numbers

25.5 + 26 +18.2 +15.3 + 28.5 + 27 + 20.7 +20.2 +26.1 +18.2 +21.4 +17.9 +24.3 +22.6+ 19.6 =331.5

2. Dividing by total

331.5/15 =22.1

What is the difference between acceleration and linear acceleration?

Akimi4 [234]

Explanation:

Linear acceleration is a type of acceleration of a body along a straight path or line.

Acceleration is defined as the rate of change of velocity with time.

Acceleration = $\frac{Change in velocity}{time}$

There are different types of acceleration .

linear acceleration is used to describe the rate of change of velocity of a body along a straight path with time.
centripetal acceleration is the rate of change of velocity of a body traveling along a circular path with time. It is directed towards the center.
Angular acceleration is the rate of change of angular velocity.

A rock is dropped from a vertical cliff. The rock takes 3.00 s to reach the ground below the cliff. A second rock is thrown vert

Phantasy [73]

Answer:

Velocity v= 12.25 $\frac{m}{s}$

Explanation:

The first rock dropped give the distance Y in meters

$Y_{f}=Y_{o}+v_{o}*t +\frac{1}{2}*a*t^{2}\\ Y_{f}=\frac{1}{2}* 9.8 \frac{m}{s^{2} }* 3^{2} \\Y_{f}=44.1 m$

Now the motion of the second rock the time change so to know the velocity

$Y_{f}= Y_{o} +v_{o}*t +\frac{1}{2}*a *t^{2} \\v_{o}*t= -Y_{f} +\frac{1}{2} *a*t^{2} \\v_{o} =\frac{-44.1 +0.5 * 9.8* s^{2} }{2} \\v_{o}= 12.25 \frac{m}{s}$
