Say the starting speed was v_i and the ending speed v_f . You know that v_i = 0 m/s, so what is v_f? Well, you also know that because the acceleration was constant, the following equation is true:

\n

v_f = v_i + at

\n

As it happens, you know that acceleration and the time the car wasaccelerated over:

\n

v_f = 0 m/s + (4.60 m/s²)(5.00 s) = 23.0 m/s

\n

Because the acceleration was constant, the average speed is

\n\n

Because v_i = 0 m/s, this breaks down to

\n\n

Plugging in the numbers gives you the average velocity:

\n\n

Great now you know the force applied and the average speed. The greater the force that is applied on an object the further distance that object will travel. The process of moving from one open window to another is called what? Why is work force times distance? This is the SI unit for work, also called the joule (J). The pascal is abbreviated as Pa.

\r\nYou dont have to be underwater to experience pressure from a fluid. This equation for acceleration can Then the acceleration would increase according the to equation (a=F/m) so the change in force divided by the objects mass will . t = 10.0 min. If the force is 2 Newtons, the distance is 5 m and the mass is 0.7 kg, for example: Multiply and divide to simplify the equation. Take the net force first. The change in pressure could also cause the nitrogen in your blood to form bubbles and give you the bends!\r\n\r\nHeres a pressure example problem using water pressure. You reason that if P = F/A, then the following is true: Plugging in the numbers and solving gives you the answer: Yikes. According to Newton's second law of motion, the acceleration of an object equals the net force acting on it divided by its mass, or a = F m . 1.5, each period of the oscillation can be divided into equal sections during which either the mass does work on the spring, or vice versa. forces generated by long-distance action Contact Forces - When two interacting items are considered to be physically engaging each other, contact forces occur. Wi Continue Reading You can use the equation

\n\n

to find the average power. On the big Physics Test Track on the edge of town, you measure its acceleration as 4.60 meters/second2 over 5.00 seconds when the car started from rest. One newton is equal to a force of 100,000 dynes in the centimetre-gram-second (CGS) system, or a force of about 0.2248 pound in the foot-pound-second (English, or customary) system. The force you feel is the weight of the water above you. That leaves only the final kinetic energy to calculate:

\n\n

Plugging in the numbers gives you:

\n\n

So because

\n\n

and the work done was

\n\n

you get the following:

\n\n

And, as before

\n\n

Double rats, your brother says.
