# Velocity and Acceleration of Particle in Curvilinear motion#

The curvilinear motion of a particle is defined by the x velocity, $$v\_{x} = {{params.vxcon}} - {{params.vxcof}}t$$ and the y position, $$y = 50 - 2t^2$$, where $$v\_{x}$$ is in meters per second, $$y$$ is in $$m$$, and $$t$$ is in $$seconds$$. If the x position is 4 at $$t = {{params.t}}$$:

## Part 1#

Determine its velocity when $$y={{params.y_position}}$$.

Determine its acceleration when $$y={{params.y_position}}$$.
