Free-body diagrams are diagrams used to show the relative magnitude and direction of all forces acting upon an object in a given situation. A free-body diagram is a special example of the vector diagrams

At an accident scene on a level road, investigators measure a car's skid mark to be 88 m long. It was a rainy day and the coeffi

Answer:

The speed was 26.91m/s (96.9 km/h)

Explanation:

Here you have to consider that at the beginning you have an amount of kinetic energy (K) that is dissipated because of the work done by friction forces (T). Since the car is stopped after the accident, all the energy has been dissipated. Thus, $K=T$ .

The definition of the kinetic energy is $K=1/2*m*v^2$ .

The work done by the friction forces is: $T=f*(m*g)*d$ . Where f is the friction coefficient, g is the gravity acceleration, m is the mass of the car and d is the skid marks longitude. Therefore,

$1.2*m*v^2=f*(m*g)*d$

Since m is in both sides it can be cancelled so it is not necessary to considered.

Then, the speed is determined by the following equation:

$v=\sqrt{2*f*g*d} =\sqrt{2*0.42*9.8m/s^2*88 m}=26.91 m/s$

If you have a positive electrical force, and a negative electrical force, what do you expect will happen?

icang [17]

I expect that they will add, and their effect at every location will be the sum of their individual effects at that location.

For example:

If they're acting at the same point and in opposite directions, the effect will be the same as a single force at that point, with strength equal to their difference, and in the direction corresponding to whichever one is stronger.

If you walk along a log floating on a lake why does the log move in the opposite direction?

aivan3 [116]

HERE'S YOUR ANSWER: 

•Since the log is stationary and you are moving beside the log, it seems to move in the opposite direction from your point of view, because from your perspective u are stationary and the log is moving. If you were to stop moving the log would also stop moving.
