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...

The speed of an object undergoing 1-dimensional motion is given
by the following equation:
What is the magnitude of the acceleration of the object (in
m/s2) at x = 10 m?
I got this much
But can't figure out how to deal with both variables
