Problem 2
State whether the following statements are true or false. In either case, give the
reasoning. For some of them a counter example suffices.
a) The magnitude of acceleration of point P, ap, cquals the time derivative of vp, the
speed of P.
b) Let B be a rigid body in plane motion. Let k be the normal direction of the reference
plane. Then the angular momentum of B must be along k.
c) In an inertial frame for a period of time, if a deformable body B is translating, then
EMc = 0, where EMc is the total moment applied to B with respect to the mass
center C.
