A particle moving along x-axis solution and explanation

This article answers the question “A particle moving along x-axis has acceleration f, at time t, given f=f nod(1-t/T), where f nod and T are constants. The particle at t=0 has zero velocity. When f=0, the particle’s velocity is?”

A particle moving along x-axis has acceleration f, at time t, given f=f nod(1-t/T), where f nod and T are constants. The particle at t=0 has zero velocity. When f=0, the particle’s velocity is?

Ques: A particle moving along x-axis has acceleration f, at time t, given f=f nod(1-t/T), where f nod and T are constants. The particle at t=0 has zero velocity. When f=0, the particle’s velocity is?

Answer: The Particle’s velocity is-

Explanation:

Given that:

At zero acceleration

hence

Now, as we know that

Hence:

integrating both sides

At zero acceleration

hence
