A mass, m1= 5.50 kg , resting on a frictionless horizontal table is connected to a cable that passes over a pulley and then is fastened to a hanging mass,
10.96 kg, as in the figure. When we release the mass m1, it
accelerates across the table. Find (a) the acceleration of the masses and
(b) the tension in the cable. Neglect the mass of the cable and pulley. Hint:
Draw a free-body diagram of each mass.

If a simple machine reduces the strength of a force, what must be increased?

Imagine that you have two balloons (or, better yet, actually inflate two balloons, if possible). create static electricity around one of the balloons by rubbing it against your hair or your sweater and then bring that balloon close to the other balloon, which has not been charged. try this with at least one other object—and for variety in the discussion, avoid using an object already described by your classmates. then, for your initial post to the discussion, answer the following questions: what happened with the two balloons?

Find the dimensions and area of the largest rectangle that can be inscribed in the upper half of the ellipse. (give your answers in terms of a and b. enter the dimensions as a comma-separated list.)
