<span> the </span>spring constant<span> k is the slope of the straight line W versus x plot.</span>
Answer:
g ≈ 2.82 m/s^2
Explanation:
By W = mg,
W = weight (in newtons)
m = mass (in kg)
g = gravitational acceleration (in m/s^2)


g ≈ 2.82 m/s^2
Answer:
x = 4.4719 m
Explanation:
For answer this we will use the law of the conservation of energy, where:

First, we will call:
: the car in rest
: when the spring is compressed
so:


where M is the mass of the car, g the gravity, h the altitude, K is the constant of the spring and X is the spring compressed in stopping the ore car. So, replacing values, we get:

solving for x:
x = 4.4719 m
Answer:
The answer to this problem is 290.16m/s
-the contact force
-weight of an object
-the surfaces in contact (coefficient of friction).
these are what I think are the answer
