Question: The lower block in the figure is pulled on by a rope with a tension force of 20 N. The coefficient of kinetic friction between the lower block & the surface is 0.30. The coefficient of kinetic friction between the lower block & the upper block is also 0.30.What is the accelerate-on of the 2.0kg block? In m/s squared.
I once observed a woman on an airplane at night with a camera. As we flew low over Washington DC she was impressed with the view of the city lights in the dark. She stood back in the aisle and tried to take the picture by the window using her flash. ..
A loudspeaker of mass 22.0 {rm kg} is suspended a distance of h = 1.60 {rm m} below the ceiling by two cables that make equal angles with the ceiling. Each cable has a length of l = 3.90 {rm m}.
Determine the resolution limit set by diffraction . what average force do you need to apply to stop the sled? Utilize the concepts of impulse and momentum.
A force of k is applied to an object for a small fraction of a second, t_k, less than the duration of one frame, t_f. Our simulation doesn't support applying forces for less than an entire frame, so if we wanted to simulate the effect of force k over..
Find the force to keep object moving.
A piece of unpainted wood barely floats in a container partly filled with water. If container is sealed and then pressurized above atmospheric pressure, does the wood rise, sink, or remain at the similar level.

On December 3 at 11 pm you look toward the eastern horizon and see the bright star Procyon rising. At approximately what time would Procyon rise one week later, on December 9.
A 110 kg mail bag hangs by a vertical rope 4.0 m long. A postal worker then displaces the bag to a position 2.0 m sideways from its original position, always keeping the rope taut. As the bag is moved to this position, how much work is completed by t..
How many 95W light bulbs can you use in a 120V circuit without tripping a 17A circuit breaker? (The bulbs are connected in parallel, which means that the potential difference across each light bulb is V.)
