find the position (r) when the vector comes to rest.
Homework Equations
initially velocity = 'u', acceleration = a
u= -14i-7j
a= 6i+3j
The Attempt at a Solution
hey guys I am new at this so i didnt know how to post it but some help would be great :)
i tried solving it for when v=0 but i didnt know how, neither could i differentiate it :/
"Find Final Position: u, a, & r" is a mathematical formula used to calculate the final position of an object given its initial velocity (u), acceleration (a), and displacement (r). It is commonly used in physics and engineering to predict the motion of objects.
The formula for "Find Final Position: u, a, & r" is r = u*t + 1/2*a*t^2, where r is the final position, u is the initial velocity, a is the acceleration, and t is the time elapsed. This formula is derived from the equations of motion in classical mechanics.
Yes, "Find Final Position: u, a, & r" can be used for any type of motion as long as the acceleration is constant. This includes linear motion, circular motion, and projectile motion.
The units for u and r are typically meters per second (m/s) and meters (m), respectively. The units for a depend on the type of acceleration (e.g. meters per second squared for linear acceleration and radians per second squared for angular acceleration).
"Find Final Position: u, a, & r" is a highly accurate formula for predicting an object's motion as long as the initial conditions are known and the acceleration remains constant. However, it may not be as accurate for complex systems with varying acceleration or external forces.
