You place the spring vertically with one end on the floor. You then drop a book of mass 1.50 kg onto it from a height of 0.900 m
Alex777 [14]

Answer:

The value of the maximum distance the spring will be compressed  

x = 0.143 m= 14.3 cm

Step-by-step explanation:

Given data

Mass m = 1.5 kg

h = 0.9 m

k = 1500\frac{N}{m}

Since the book is released from a height h = 0.9 m above the top of the spring. so the total distance

y = h + x

Now in that case for the spring

mg y= \frac{1}{2} k x^{2}

mg(h +x) = \frac{1}{2} k x^{2}

By rearranging the above equation we get

k x^{2}  - 2mgx - 2mg h = 0

Put all the values in above equation we get

1500x^{2}  - 29.43 x - 26.48 = 0

By solving the above equation we get

x = 0.143 m= 14.3 cm

This is the value of the maximum distance the spring will be compressed.

What’s the equation of the line that passes through (2,3) and is parallel to the line 12x-5y=2
TiliK225 [7]

12x-5y=2

-5y=2-12x

y=-2/5+12/5x

should know the m=12/5

and (2,3) bring them to the line equation:

3=12/5x2+b

6/5+b=3

b=3-6/5

b=9/5

y=12/5x+9/5

Which means the answer is not in the choices.
