How to calculate resultant velocotu in x y/and z directions?
Answers
Answer:
Physics can be a challenging course for anyone because it combines science with math and introduces potentially difficult concepts. One basic idea is the concept of speed and how it changes. Calculating the speed of an object can be a simple process if a few basic rules are kept in mind. Learn how to solve problems where you need to find the resultant velocity.
Find Acceleration
First, make sure all the units are in standard form before doing any calculations. Write down all the information you need before starting your calculations and then draw a picture of the problem to help you understand what is going on. Find the acceleration of the object, the time the object is being accelerated and the initial velocity. These values are usually given to you in the problem. If the force is given, find the acceleration by dividing the force on the object by its mass.
Convert Units
Convert all units to standard units of measurement. Acceleration should be in meters per second squared. Velocity should be in meters per second and time should be in seconds.
Resultant Velocity
Multiply the acceleration by the time the object is being accelerated. For example, if an object falls for 3 seconds, multiply 3 by 9.8 meters per second squared, which is the acceleration from gravity. The resultant velocity in this case is 29.4 meters per second.
Velocity Formula
Add this velocity to the initial velocity. In the example above, if the object had an initial velocity of 5 meters per second, the resultant velocity would be 34.4 meters per second. The overall formula here is v (final) - at + v (initial) where "v" is velocity, "a" is acceleration and "t" is time. In this example the equation would look like this: v (final) = 9.8 x 3 + 5, giving us a result of 34.4.
