(10 points) The work done by a force is the scalar product of the force and displacement vectors, i.e W F x and the power is given by the dot product between the force and the velocity vector, i.e. P F.V . For a force vector, F 2x i+10y j- (x+5y) k and a displacement vector, x=t i+t j+2t k, calculate the work done by the force and the power required. Based on your answer, what can you say about...

1.) Vectors Can the x or y component of a vector ever have a greater magnitude than the vector itself has? Yes. The x component can, but the y component cannot. Yes, but only when the x and y components have equal magnitudes. Yes. Both components can. Yes. The y component can, but the x component cannot. No. Neither component can. 2.) A force vector has a magnitude of 370 newtons (N) and points at an angle of 53.0° below...
Using the position vector from A to C, calculate the moment about segment A B due to force F.
The general process (not referenced to Figure 1) to calculate the moment of a force about a specified axis is as follows:The magnitude of a moment about a line segment connecting points P and Q due to a force F applied at point R (with R not on the line through P and Q ) can be calculated using the scalar triple product,MPQ=uPQ · r × Fwhere r is a position vector from any point on the line through P...

(d) How is centripetal force produced? What is is direction? Can it be produced by non-uniform circular motion? If the circular motion is uniform (ie. the tangential speed is a constant), how does acceleration occur? (e) Define centrifugal force and indicate is direction What is is source? Which of Newton's Laws of Motion apply here? You may use a sketch to assist you in your answer. (I) Is a torque a scalar or a vector? If it is a vector,...

the furthest i could get is that the dot product between vector
N and vector V, as well as vector X and vector V must be zero but
that's about it. I get stuck when trying to use the cosine relation
with the dot product but since the question doesn't allow me to
write it in terms of an angle, i can't really use that. If someone
could show me how this would help incredibly!
