**1. Homework Statement**

An object of mass m=1.0kg experiences a force of the following mathematical form,

F(t)=k*e^(-c*t) i

where k=6.0N and c=0.10 (1/s) and i indicates the unit vector in the x-direction.At time t=0, the object has a velocity of v=2.0 m/s and is at the origin. Where is this object after 20 seconds?

**2. Homework Equations**

F=ma.. maybe..

**3. The Attempt at a Solution**

I used the force equation and F=ma to get the acceleration and was going to use the x=(vo)t +(1/2a)t^2 equation, but then I realized that doesn't make sense... I'm kind of confused though... How do you find the distance if the force varies? Thanks in advance.
