Consider a particle following the parametric equations
What is the speed of this particle? (You may assume it's constant at all times.)
Please help, and explain how to find the speed.
The speed of the particle is 5.
dx/ dt is the speed of the particle in the x direction = 2
dy/dt is the y direction speed = 3
Use pythagorean theorem to calculate the resultant speed = sqrt (2^2 + 3^2 ) = sqrt 13
