a Particle under goes two displacements represented vectorically as 2i^ +3j^ -4k^ what is net displacements? find the magnitude of the net displacements
Answers
Answer:
perhaps 7 is the the magnitude of your question
Answer:
In addition to obtaining the displacement and velocity vectors of an object in motion, we often want to know its acceleration vector at any point in time along its trajectory. This acceleration vector is the instantaneous acceleration and it can be obtained from the derivative with respect to time of the velocity function, as we have seen in a previous chapter. The only difference in two or three dimensions is that these are now vector quantities. Taking the derivative with respect to time.
By the end of this section, you will be able to:
Calculate the acceleration vector given the velocity function in unit vector notation.
Describe the motion of a particle with a constant acceleration in three dimensions.
Use the one-dimensional motion equations along perpendicular axes to solve a problem in two or three dimensions with a constant acceleration.
Express the acceleration in unit vector notation.
