NEED HELP ASAP. 1. A physics student starts from an initial starting point and walks the
following directions (vectors.) Draw a diagram of the vectors and
indicate the resultant vector. Mathematically determine the magnitude
of the displacement vector.
1.4 m west
2.3 m south
3.3 m west
4.1 m north

Alfred pushes on a heavy box, but cannot move it. the box has a lot of inertia motion friction gravity

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.

You hang a book bag on a spring scale and place the bag on a platform scale so that the platform scale reads 23.7n and the spring scale reads 13.8n. what is the magnitude of the force that earth exerts on the bag?
