An applied force F1= 16N acting on an object with the mass m = 2 kg which is moving on the surface of a table. If the friction force between the object and the table is F2 = 8N determine the Fnet and acceleration. Determine the coefficient of friction between the object and the table.
What mass (in grams) of steam at 100 °C must be mixed with 287g of ice at its melting point, in a thermally insulated container, to produce liquid water at 65°C? The specific heat of water is 4186 J/kg·K. The latent heat of fusion is 333 kJ/kg, an..
A 4.9 cm tall object is placed 25 cm in front of a spherical mirror. It is desired to produce a virtual image that is upright and 3.9 cm tall. Where is the image located? What is the focal length of the mirror?

assume that you are swimming in a river while a friend watches from the shore. In calm water, you swim at a speed of 1.25 rm m/s . The river has a current that runs at a speed of 1.00 rm m/s.
When the wire is removed, the spheres repel each other with an electrostatic force of 0.0394 N. Of the initial charges on the spheres, with a positive net charge, what was (a) the negative charge in coulombs on one of them and (b) the positive cha..
As F is enhancement d, the block would either begin to slide, or begin to tip over. What must be the coefficient of static friction ms so that the block begins to slide rather than tip.
How far below the release point is the center of mass of two stones at t = 550 ms? (Neither stone has yet reached the ground.)
It takes a minimum distance of 48.96 m to stop a car moving at 12.0 m/s by applying the brakes (without locking the wheels). Assume that the same frictional forces apply and find the minimum stopping distance when the car is moving at 26.0 m/s.
