Why and when do we differentiate or integrate equations in physics? [closed]
I'm an engineering student and none of my professors ever explained why do we use derivations and/or integrations in physics. So I have this task, it goes like:
The object is moving in a positive ...

Particle moving under force $F=-cx^3$ [closed]
A particle with mass $m$ moves under influence of a force $F=-cx^3$, with $c$ a constant. What is the potential energy function $V(x)$?
And if it starts to move from rest from position $x=-a$, what ...

Terminal velocity and distance traveled with constant but limited power
I'm trying to model how far to move an object over time according to a power applied resisted by friction.
So maybe... an object accelerates at a certain rate until the power provided can no longer ...

Convert an equation for acceleration into one for velocity
A sledge is pushed in a straight line. Assume surface is smooth. When the sledge is x distance away from the start the magnitude of its acceleration is given by $0.08e^{-4x}$ and is going in the same ...

Equation for position of mass suspended by a spring on an incline
I'm interested an application of hooke's spring equations to solve for the position of an object with respect to time in the following scenario:
Where $T_2$ is a spring with coefficient $k$. I ...

Solve $a(t) = g - \beta v(t)$ for $t$
If $g$ is the acceleration due to gravity and $\beta$ is a known
value, solve for the time $t$ it takes an object to reach a given
velocity if the acceleration of the object is given by
$$a(t)...

How long does it take for an electric car to go from 0 to 60 mph?
I found the freefall motion equation which describes terminal velocity of a falling body, but I can't find a similar equation for a vehicle subject to constant traction force, so I tried determining ...

How can I find $v(t)$ if I'm given $x(v)$? [closed]
The given is the distance but the variable is the velocity $x(v)=k \,v^2$. I want to find the velocity $v(t)$.

Area under the displacement-time graph giving time?
This is probably very stupid, but today at a lecture, our professor solved a problem where we had to find the time taken to travel from 0-5m, where $v = 3/x$ (velocity is a function of position.)
