The time the two trains are at the same distance from salt lake city is 6:am
<h3>What is rate?</h3>
a rate is a ratio that compares two different quantities which have different units. For example, if we say John types 50 words in a minute, then his rate of typing is 50 words per minute. The word "per" gives a clue that we are dealing with a rate.
Let the distance between salt lake city and the two trains be x and the time they are at the same distance x be t.
distance traveled by first train,
speed = distance/time
40 = x/t
making x subject of the equation and cross multiplying,
x = 40t--------------1
Also train 2 moved 4 hours later by 2pm, so the its time is t - 4
speed = distance /time
50 = x/t - 4
x = 50(t - 4)---------------2
Equating equations 1 and 2, we have
50(t - 4) = 40t
50t - 200 = 40t
50t - 40t = 200
10t = 200
t = 200/10
t = 20 hours
so the time the two trains will be at the same distance should be 20 hours from 10 am which is 6am the following day.
In conclusion the two trains will be at the same distance at 6am the following day.

Full Question
A 10 kilogram object suspended from the end of a vertically hanging spring stretches the spring 9.8 centimeters. At time t = 0, the resulting mass—spring system is disturbed from its rest state by the force F (t) = 20 cos(8t). The force F (t) is expressed in Newtons and is positive in the downward direction, and time is measured in seconds.
Determine the spring constant k.
Answer:
Spring Constant = 1000Nm^-1
Step-by-step explanation:
Given
Mass = 10kg
Spring Extension = 9.8cm
Spring Constant K = Force/Extension
Force = Mass * Acceleration
Force = 10 * 9.8 = 9.8N
Spring Extension = 9.8 cm = 9.8 /100 = 0.098 m
Spring constant = 98 / 0.098
Spring Constant = 1000Nm^-1
