Homework Statement



A particle is constrained to move around the unit circle in the xy plane according to the

formula (x,y,z)=(cos(t2),sin(t2),0), t[tex]\geq[/tex]0.

At what point on the circle should the particle be released to hit a target at (2,0,0)?


Homework Equations



None


The Attempt at a Solution



I computed the velocity vector and speed of the particle as functions of t:

velocity: (-2tsin(t2),2tcos(t2),0)

speed: 2t.

After wards, I got stuck. Any advice would be appreciated.

Hint: Once the particle is released (No forces act on it), what kind of trajectory would you expect it to have? (i.e. circular, parabolic, etc.)
 

1. What is vector calculus and how is it used in mechanics?

Vector calculus is a branch of mathematics that deals with the differentiation and integration of vector fields. In mechanics, vector calculus is used to describe the motion of objects in three-dimensional space and to analyze forces and their effects on these objects.

2. What are some common applications of vector calculus in mechanics?

Some common applications of vector calculus in mechanics include calculating the velocity and acceleration of objects, determining the work and energy involved in a system, and analyzing the forces acting on an object in motion.

3. How do I solve a vector calculus world problem about mechanics?

To solve a vector calculus world problem about mechanics, you will need to first identify the given information and what is being asked for in the problem. Then, you will use the principles of vector calculus, such as differentiation and integration, to analyze the problem and find a solution.

4. What are some common challenges when solving vector calculus world problems about mechanics?

Some common challenges when solving vector calculus world problems about mechanics include accurately setting up the problem, choosing the appropriate vector calculus concepts and equations, and properly interpreting the results.
