<span>F = kx, where F is the force we apply, k is the spring constant, and x is the extension of the material 
so the </span><span>spring's effective spring constant k is:
k = F / x
k = ( 110 kg ) ( 9.81 m/s^2) / 0.65 cm
k = 1660 N/cm  is the </span>spring's effective spring constant

galina1969 [7]
The formula for this problem that we will be using is:
F * cos α = m * g * μs where:F = 800m = 87g = 9.8
cos α = m*g*μs/F= 87*9.8*0.55/800= 0.59 So solving the alpha, find the arccos above.
α = arccos 0.59 = 54 ° is the largest value of alpha

Until a train is a safe distance from the station, it must travel at 5 m/s. Once the train is on open track, it can speec
nadezda [96]

Answer:

The acceleration of the train is 5 m/s².

Explanation:

Given:

let the initial velocity of a train = 5 m/s and

final velocity of a train = 45 m/s

time taken = 8 s

To find:

acceleration: ?

Solution:

We define acceleration as change in velocity per unit time that is the difference between the final velocity and initial velocity divided by time.

Acceleration = \frac{\textrm{final velocity} - \textrm{initial velocity}}{time} \\

On substituting the above values we get the required acceleration

Acceleration = \frac{45 - 5}{8}\\ =\frac{40}{8}\\ =5\ m/s^{2}

Therefore,the acceleration of the train is 5 m/s².
