As you can see, the mass of car (and riders) $m$ does play part here but again it seems folly to rely on loading specifications rather than safe design. A boater and motor boat are at rest on a lake. As it is released, its velocity is 4.4 m/s. Express your answer in newtons and as a ratio to the weight of the shell. Again, what do you call a "normal" car? Some books teach you to always think about this term, others only add it if it isnt zero. Find the magnitude and direction of the total force on the Achilles tendon. If non-conservative forces are either known or small and if energy is converted from one form to another between the locations, then any time you relate speed and position of an object at two different points conservation of energy is the most direct way to understand the problem. What's New A crate of mass 100.0 kg rests on a rough surface inclined at an angle of37.037.0with the horizontal.
