Step-by-step explanation:
The equation that is given is only for the specific place of that object. To find the velocity, you need to take the derivative of the equation. This will give you:
Now, to find the average velocity of this object, plug in the values given to you. It's between the time interval [1, 2] so these are the two numbers you'll plug into the velocity equation. Finding this average is like finding any other average.
So
Average velocity is 0.5 sec
To find instantaneous velocity just find the velocity at time one. Think about the name "instantaneous velocity," it's the velocity in that <u>instant</u>.
We already found this, so I don't need more work (it's displayed above).
The instantaneous velocity when is 2.5 sec.
Answer:
49.4 (rounded to the nearest tenth)
Step-by-step explanation:
You need to use the Pythagorean theorem -> ->
is the hypotenuse
+
=
(7x + (5x7) =
+ 35 =
2436 =
= c
c = 49.355850717
c = 49.4 (round to the nearest tenth)
hope this helps, sorry if it is not right
