Question
A particle moves in a straight line with an initial velocity of $30 \mathrm{m} / \mathrm{s}$ and constant acceleration $30 \mathrm{m} / \mathrm{s}^{2}$. (a) What is its displacement at $t=5 \mathrm{s} ?$ (b) What is its velocity at this same time?
Step 1
We can use the equation of motion $s=ut+0.5at^2$, where $s$ is the displacement, $u$ is the initial velocity, $a$ is the acceleration, and $t$ is the time. Show more…
