The speed downwards is 7 + (3*9.8)
7+ 29.4 = 36.4 m/s
Hello Paige,
Question - Please select the word from the list that best fits the definition Fossils up to 75,000 years old can be dated with ______.
Answer - Carbon 14
It would most likely be answer B considering the other ones don’t make sense in this question
Answer:
Explanation:
The system can be modelled appropriately by the use of the Principle of Momentum Conservation and Impact Theorem:
The average force exerted on her:
Answer:
a) 0m
b) 6m
Explanation:
First, we need to remember:
Displacement: Difference between final and initial position.
Distance traveled: Total distance traveled.
a) If the final position is the same as the initial position, then:
final position = initial position
And we know that:
displacement = final position - initial position = 0
Then the displacement of the book is zero.
b)
We can assume that the book traveled along the perimeter of the table.
The table is a rectangle of width 1.2m and length 1.8m
Remember that for a rectangle of width W and length L, the perimeter is:
P = 2*L + 2*W
Then the perimeter of the table is:
P = 2*1.2m + 2*1.8m = 6m
This means that the distance traveled by the book is 6 meters.
