A particle's acceleration along an $x$ axis is $a=5.0 t$, with $t$ in seconds and $a$ in meters per second squared. At $t=2.0 \mathrm{~s}$, its velocity is $+17 \mathrm{~m} / \mathrm{s}$. What is its velocity at $t=4.0 \mathrm{~s}$ ?

Step 1
So, we can find the change in velocity by integrating the acceleration function with respect to time. The integral of $a=5.0 t$ from $t=2.0s$ to $t=4.0s$ is: Show more…

A particle moves along the $x$ -axis according to the equation $x(t)=2.0-4.0 t^{2} \mathrm{m} .$ What are the velocity and acceleration at $t=2.0 \mathrm{s}$ and $t=5.0 \mathrm{s} ?$
The velocity of a particle moving along the $x$ -axis varies with time according to $v(t)=A+B t^{-1},$ where $A=$ $2 \mathrm{m} / \mathrm{s}, B=0.25 \mathrm{m},$ and $1.0 \mathrm{s} \leq t \leq 8.0 \mathrm{s} .$ Determine the acceleration and position of the particle at $t=2.0 \mathrm{s}$ and $t=$ 5.0 s. Assume that $x(t=1 \mathrm{s})=0$.

Additional Problems Figure $2-44$ gives the acceleration a versus time $t$ for a particle moving along an $x$ axis. The $a$ -axis scale is set by $a_{s}=12.0 \mathrm{m} / \mathrm{s}^{2} .$ At $t=-2.0 \mathrm{s}$ the particle's velocity is 7.0 $\mathrm{m} / \mathrm{s} .$ What is its velocity at $t=$ 6.0 $\mathrm{s} ?$
