Special relativity states that the effective mass of an object varies as a function of its velocity. If c is the speed of light (c approx. = 300,000 km/s) and v is the velocity of the object (in km/s), find the effective mass m' of an object traveling at a velocity v. Assume that at v = 0 m/s, m = 1 kg.

Note that the *correct* answer according to special relativity is still 1 kg.
(the mass does NOT change, unless some external scalar fields are involved)

From now on, I think "assert(isempty(strfind(filetext, 'interp1')))" should be considered!
