Equations and Problem-Solving

* An airplane accelerates down a runway at 3.20 m/s2 for 32.8 s until is finally lifts off the ground. Determine the distance travelled before take-off.

-------------------------------------------------
Solutions
Given: a = +3.2 m/s2| t = 32.8 s| vi = 0 m/s|
| Find:d = ??|

d = VI*t + 0.5*a*t2
d = (0 m/s)*(32.8 s) + 0.5*(3.20 m/s2)*(32.8 s)2
d = 1720 m

Equations and Problem-Solving

* A car starts from rest and accelerates uniformly over a time of 5.21 seconds for a distance of 110 m. Determine the acceleration of the car.

Given: d = 110 m| t = 5.21 s| vi = 0 m/s|
| Find:a =??|

d = VI*t + 0.5*a*t2
110 m = (0 m/s)*(5.21 s) + 0.5*(a)*(5.21 s)2
110 m = (13.57 s2)*a
a = (110 m)/ (13.57 s2)
a = 8.10 m/ s2

Equations and Problem-Solving

* Rocket-powered sleds are used to test the human response to acceleration. If a rocket-powered sled is accelerated to a speed of 444 m/s in 1.8 seconds, then what is the acceleration and what is the distance that the sled travels?

-------------------------------------------------
Solutions
Given: vi = 0 m/s| vf = 44 m/s| t = 1.80 s|
| Find:a =??d =??|

a = (Delta v)/t
a = (444 m/s - 0 m/s)/ (1.80 s)
a = 247 m/s2
d = VI*t + 0.5*a*t2
d = (0 m/s)*(1.80 s) + 0.5*(247 m/s2)*(1.80 s)2
d = 0 m + 400 m
d = 400 m
(Note: the d can also be calculated using the equation vf2 = vi2 + 2*a*d) -------------------------------------------------
Equations and Problem-Solving

* A kangaroo is capable of jumping to a height of 2.62 m. Determine the take-off speed of the kangaroo.

-------------------------------------------------
Solutions
Given: a = -9.8 m/s2| vf = 0 m/s| d = 2.62 m|
| Find:VI =??|

...In my efforts to solve a problem I have often begun by identifying the one issue that affects me and focus on the individual tasks that led to the problem attempting to use logical and critical thinking. I have hit upon the realization that this focus works well with simpler problems that need immediate clarification but it has proven appropriate that problems that are more difficult and require a more long-term and elaborate answer...

...Where there is a problem there is a solution. No matter how complicated nor how elusive the solution is one is always there. Problems are the basis of jobs and careers: restaurants for hunger, movies and video games for boredom, news for information etc. However, with basic problems that have a set solution there are a variety of ways to solve it.
Working backwards, although slightly different, is a widely used and very effective way of...

...society and its economic and governmental organizations--is largely work of making decisions and solvingproblems. It is work of choosing issues that require attention, setting goals, finding or designing suitable courses of action, and evaluating and choosing among alternative actions. The first three of these activities--fixing agendas, setting goals, and designing actions--are usually called problemsolving; the last, evaluating and...
