- Homework Statement
- The momentum of a particle is P vector=##\vec A##+(##\vec B##×##t^2##),where ##\vec A## and ##\vec B## are constant perpendicular vectors.The force acting on the particle when its acceleration is at 45° with its velocity is
- Relevant Equations
- F=dP/dt
I calculated force vector by differentiating momentum vector.Since acceleration and velocity vectors are at45°,therefore force and momentum vector are at 45°.But i am not able to find the time at which it will take place.I tried F vector.P vector=FPcos45° but i am not getting from it.I also used that Avector.B vector=0.Help please.
