Hi.my questions are.
1-Are the instantaneous velocity vector and the acceleration vector always in the direction of the motion? Why?
2-is it possible for the velocity vector of a particle to be perpendicular to its position vector? Why?
3-is it possible for a particle to go around a curve at constant speed without expressing an acceleration.Why?
Thanks
