A force moves an object along an x axis. If the magnitude of the force varies from point to point, can the work be calculated by taking the dot product of the force and the displacement?
yes
no
Homework Answers
No
So we cant simply take dot product of Force and displacement, we also have to perform integration

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...
