The only force F~ acting on a body of mass m (in kg) changes in time t according to F~ (t) = (F0 sin(ωt), F0 cos(ωt)) where F0 is a constant with units of N and the greek letter ω is a constant with units of radians/s. (Technically a radian is dimensionless, but I’ve explicitly stated it to clarify the problem.) Assume all arbitrary constants that appear due to indefinite integration are zero. (a) What is the acceleration vector of...
