This problem requires us to find the velocity and position functions of an object given a force function.
This is a Force with Calculus type of problem since we have the force as a function of time. We'll follow these steps:
A diagram like this one can help you remember the relationships between the variables:
Remember the power rule of integration.
, where C is the constant of integration.
The velocity function is the integral of the acceleration function, a(t). We're not given a(t), but we are given a function for force, F(t).
The object's position function, x(t), is the integral of the velocity function v(t).
So here's our process:
A particle of mass m, initially at rest at x = 0, is accelerated by a force that increases in time as F = Ct2.
(a) Determine its velocity as a function of time.
(b) Determine its position as a function of time.
