The basis for kinetics is Newton's second law, which states that when an unbalanced force acts on a particle, the particle will accelerate in the direction of the force with a magnitude that is proportional to the force.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

11. Sample 1
The position coordinate of a particle which is confined to move
along a straight line is given by s = 2t 3 − 24t + 6, where s is
measured in meters from a convenient origin and t is in seconds.
Determine (a) the time required for the particle to reach a velocity
of 72 m/s from its initial condition at t = 0, (b) the acceleration of
the particle when v = 30 m/s, and (c) the net displacement of the
particle during the interval from t = 1 s to t = 4 s.
13. Sample 2
A particle moves along the x-axis with an initial velocity vx = 50
m/s at the origin when t = 0. For the first 4 seconds it has no
acceleration, and thereafter it is acted on by a retarding force which
gives it a constant acceleration ax = −10 m/s2. Calculate the
velocity and the x-coordinate of the particle for the conditions of t
= 8 s and t = 12 s and find the maximum positive x-coordinate
reached by the particle.
14. Sample 3
The spring-mounted slider moves in the horizontal guide with
negligible friction and has a velocity v0 in the s-direction as it
crosses the mid-position where s = 0 and t = 0. The two springs
together exert a retarding force to the motion of the slider, which
gives it an acceleration proportional to the displacement but
oppositely directed and equal to a = −k2s, where k is constant.
Determine the expressions for the displacement s and velocity v as
functions of the time t.
15. Sample 4
The car is traveling at a constant speed v0 = 100 km/h on the level
portion of the road. When the 6-percent (tanθ = 6/100) incline is
encountered, the driver does not change the throttle setting and
consequently the car decelerates at the constant rate gsinθ.
Determine the speed of the car (a) 10 seconds after passing point A
and (b) when s = 100 m.
16. Sample 5
A motorcycle patrolman starts from rest at A two seconds after a
car, speeding at the constant rate of 120 km/h, passes point A. If the
patrolman accelerates at the rate of 6 m/s2 until he reaches his
maximum permissible speed of 150 km/h, which he maintains,
calculate the distance s from point A to the point at which he
overtakes the car.

18. Sample 6
A particle starts from rest at x = -2 m and moves along the x-axis
with the velocity history shown. Plot the corresponding
acceleration and the displacement histories for the 2 seconds. Find
the time t when the particle crosses the origin.
19. Sample 7
When the effect of aerodynamic drag is included, the y-acceleration
of a baseball moving vertically upward is au = – g – kv2, while the
acceleration when the ball moving downward is ad = – g + kv2,
where k is a positive constant and v is the speed in meters per
second. If the ball is thrown upward at 30 m/s from essentially
ground level, compute its maximum height h and its speed vf upon
impact with the ground. Take k to be 0.006 m-1 and measure that g
is constant.
