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,

d=\text{final position}-\text{initial position}\\\\-144=327-\text{initial position}\\\\\text{initial position}=327+144\\\\\text{initial position}=471\ m

So, its initial position was 471 m.

A child leaves her book bag on a slide. The bag, which is at the top of the slide, starts from rest and reaches the bottom in 1.
mel-nik [20]

Answer:

Part a)

a = 2.55 m/s^2

Part b)

F_f = 5.02 N

Part c)

\mu = 0.27

Part d)

v_f = 4.1 m/s

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

L = v_i t + \frac{1}{2}at^2

3.30 = 0 + \frac{1}{2}a(1.61)^2

a = 2.55 m/s^2

Part b)

As we know by force equation

mg sin\theta - F_f = ma

(2.20)(9.81)sin29.5 - F_f = (2.20)(2.55)

so we have

F_f = 5.02 N

Part c)

Now we know that perpendicular to the plane we will have

F_n = mg cos\theta

F_n = (2.20)(9.81) cos29.5

F_n = 18.78 N

now we know that

F_f = \mu F_n

5.02 = \mu (18.78)

\mu = 0.27

Part d)

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

v_f^2 - v_i^2 = 2 a L

so we have

v_f^2 - 0 = 2(2.55)(3.30)

v_f = 4.1 m/s
