Find the velocity and displacement of the particle at t=t1>0

In summary, the conversation discusses a particle at rest at t=0 with a linearly increasing force applied. The task is to find the velocity and displacement of the particle at a specific time t1. It is suggested that the force can be set equal to ma, or bt=m*dv/dt, which can be integrated to find the velocity and displacement.

So I have the problem:

A particle of mass m is at rest at t=0. A linearly increasing force F=bt is applied. Find the velocity and displacement of the particle at t=t1>0


What exactly is bt?
Can it be set equal to ma?

Yes, it can be set equal to ma, or maybe even better bt=m*dv/dt, which if you don't know diff eq (which I'm assuming you don't) will lead to

[tex]\int \frac{b}{m} t dt = \int dv[/tex]

Hopefully you know how to integrate :)

A similar procedure to obtain the integrands for displacement can be used.
 

FAQ: Find the velocity and displacement of the particle at t=t1>0

What does "velocity" and "displacement" mean in this context?

"Velocity" refers to the rate of change of an object's position over time. It is a vector quantity, meaning it has both magnitude and direction. "Displacement" is the distance and direction from an object's starting point to its ending point.

How is the velocity of a particle calculated?

The velocity of a particle can be calculated by dividing the change in its position by the change in time. This is represented by the equation: v = (xf - xi) / (tf - ti), where v is velocity, xf is the final position, xi is the initial position, tf is the final time, and ti is the initial time.

What is the difference between velocity and speed?

Velocity and speed are often used interchangeably, but they have different meanings in physics. While velocity is a vector quantity that includes direction, speed is a scalar quantity that only considers the magnitude of an object's motion.

How is displacement different from distance?

Displacement is a vector quantity that takes into account the starting point and ending point of an object's motion. Distance, on the other hand, is a scalar quantity that only considers the total length traveled by an object, regardless of its starting and ending points.

Why is it important to specify t=t1>0 in the question?

In physics, time is often measured relative to a starting point, which is usually denoted as t=0. By specifying t=t1>0, it means we are finding the velocity and displacement of the particle at a specific time after the starting point. This allows for a more accurate and precise calculation of the particle's motion.
