An object travels from the South Pole along the Prime Meridian to the equator. It
mow moves from the equator to (0o, 56oE) and then to (28oS, 56oE). What total
distance, in miles, did the object travel? Hint: At the equator
1o= 69.2 miles.

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...
