Answer:The "mean" is just the normal arithmetic average that you are most likely already familiar with.
mean=(sum of elements)/(number of elements)
In this case:
mean=(2+28+2+20+22)/5
mean=74/5
mean=14.8
So the mean or average age of the trees is 14.8 years.
<h2>
If we are considering upward direction as positive, vertical component of acceleration is -9.81 m/s².</h2>
Step-by-step explanation:
A soccer ball is kicked with a velocity of 25 m/s at an angle of 45° above the horizontal.
Here we need to find vertical component of its acceleration as it travels along its trajectory.
Vertical component of acceleration is acceleration due to gravity.
That is vertical component is 9.81 m/s² downward.
If we are considering upward direction as positive, vertical component of acceleration is -9.81 m/s².
