Course: Engineering Mechanics Dynamics Book: Engineering Mechanics- Dynamics

Question

A particle moves through an electric field between two plates. Its velocity–time graph is a symmetric triangle: $t' = 0.2\text{ s}$ and $v_{\max} = 10\text{ m/s}$. Velocity increases linearly from $0$ to $v_{\max}$ over $0 \le t \le t'/2$, then decreases linearly from $v_{\max}$ back to $0$ over $t'/2 \le t \le t'$. At $t = t'/2 = 0.1\text{ s}$, the particle is at $s = 0.5\text{ m}$. Draw the $s$–$t$ and $a$–$t$ graphs for the particle.
