An 89 kilogram person needs to start sliding their waxed skis on snow, starting from rest. Calculate the force of static friction that must be overcome for the skis to begin sliding. Show all work, including equations, values
with units, and substitution into the equation(s). [hint: remember to get weight first]

Laboratory experiments, observational field studies, and model-building are all examples of different forms of scientific investigations.  in what way do laboratory experiments primarily differ from other forms of scientific investigations?   a.  a laboratory experiment is the only accepted form of investigation within the scientific community.  b.  studies about how things behave in nature or studies involving very large objects are best answered through laboratory experiments.  c.  laboratory experiments involve the identification and control of variables.  d.  data can only be generated through laboratory experiments, not other forms of investigation.

If the spring constant k of a pogo stick is 3500 n m and the weight of the person on the pogo stick is 700 n, how much is the spring in the botom of the pogo stick compressed?

Often called simply "velocity," this is the velocity of an object at a particular moment in time.
