Answer:
Its initial position was 471 m.
Explanation:
We have,
Final position of the object is 327 m
Displacement of the object is -144 m
It is required to find its initial position. The difference of final and initial position is equal to the displacement of the object. So,

So, its initial position was 471 m.
The correct answer is consequent.

Answer:
10-10x10+10=10-100+10=20-100=-80
Answer:
Part a)

Part b)

Part c)

Part d)

Explanation:
Part a)
As we know that the length of the slide is L = 3.30 m
time = 1.61 s
so we can use kinematics here to find the acceleration of the bag



Part b)
As we know by force equation


so we have

Part c)
Now we know that perpendicular to the plane we will have



now we know that



Part d)
When the bag will reach at the bottom then the final speed is given as

so we have
