A crate with a mass of 210 kg is horizontally accelerated by a force of 95 N.
The force is directed at an upward angle so that the vertical part of the force is 47.5 N and the horizontal part of the force is 82.3 N (see the diagram below).
If the crate is pulled 5.5 m across the floor, what is the change in kinetic energy of the crate?
two forces f1 500Ndue east and f2 250N due north have their common initial point f1 - f2 is
