A particle leaves the origin with an initial velocity $\vec{v}=(3.00 \hat{\mathrm{i}}) \mathrm{m} / \mathrm{s}$ and a constant acceleration $\vec{a}=(-1.00 \hat{\mathrm{i}}$ 0.50$\hat{\mathrm{j}} ) \mathrm{m} / \mathrm{s}^{2} .$ When it reaches its maximum $x$ coordinate, what a its (a) velocity and (b) position vector?

Key Concepts

Two-Dimensional Kinematics

This concept involves analyzing motion in two independent directions, typically along mutually perpendicular axes (e.g., x and y). The kinematics in each direction are treated separately using the constant acceleration equations, accounting for both the initial velocities and accelerations in each coordinate direction.

Constant Acceleration Equations

These equations describe the relationship between displacement, initial velocity, acceleration, and time for an object moving with a constant acceleration. They are used to calculate an object’s velocity and position over time in each independent direction, facilitating the determination of the trajectory in two dimensions.

Determining Maximum Coordinate Conditions

This concept involves finding the point at which a specific coordinate (e.g., x) reaches its maximum or minimum value. For the maximum x coordinate in a constant acceleration scenario, the condition is typically that the derivative of the x-coordinate position (i.e., the x-component of velocity) becomes zero. This condition helps in finding the time at which the maximum value occurs, which is essential for calculating the corresponding position and velocity vectors.
