Acceleration from Velocity Graph#
The figure shows the velocity of a particle as it travels along the x-axis.
![Graph of velocity versus time, a parabola-like shape that is concave up. The x-axis represents time and the x-axis represents velocity. It slopes downwards from t=0 to t=1, then slopes upward form t=1 to t=4. The y intercept is 4m/s an the x intercepts are t=0.5 and t=2.](../../../../../_images/Q1.png)
Part 1#
What is the direction of the acceleration at \(t\) = 4 s?
Answer Section#
In the \(+x\) direction.
In the \(-x\) direction.
In the \(+y\) direction.
In the \(-y\) direction.
The acceleration is zero.
