DIFFERENTIAL EQUATION PROBLEM
An object with a mass of 2 kg moves along the x-axis and we will
assume that the positive direction of movement is to the right.
Only one force (in N) is present and opposes the movement. Let
be the speed of the object (in m / s) at time t. The object starts
from the origin (x = 0) with an initial speed of 75 m / s. Suppose
that the resistance force has a magnitude equal to
a) how long will it take for the object to reach position x = 70 m?
b) if we let time go to infinity, what total distance will the object travel?
