Question
An object's velocity is $\vec{v}=c t^{3} \hat{\imath}+d \hat{\jmath},$ where $t$ is time and $c$ and $d$ are positive constants with appropriate units. What's the direction of the object's acceleration?
Step 1
The acceleration is the derivative of the velocity with respect to time. So, we differentiate the velocity function $\vec{v}=c t^{3} \hat{\imath}+d \hat{\jmath}$ with respect to time $t$. Show more…

An object's velocity is v⃗ = ct^3i^ + dj^, where t is time and c and d are positive constants with appropriate units. What is the object's acceleration? Express your answer in terms of some or all of the variables c, t, and d, and unit vectors i^ and j^. Use the 'unit vector' button to denote unit vectors in your answer.
An object's velocity as a function of time is given by $v(t)=b t-c t^{3}$, where $b$ and $c$ are positive constants with appropriate units. If the object starts at $x=0$ at time $t=0$, find expressions for (a) the time when it's again at $x=0$ and (b) its acceleration at that time.
An object's velocity as a function of time is given by v(t) = bt - ct^3, where b and c are positive constants with appropriate units. If the object starts at x = 0 at the time t = 0, find expressions for a) the time when it's again at x = 0 and b) its acceleration at that time.
