Two crates of different masses sit on a frictionless ice rink. The same constant horizontal force is applied to each of the crates so the crates accelerate towards the east.
If the force is applied to each crate over the same distance, which of the following is true?
a) The crates will end up with the same momenta.
b) Both their momenta and their kinetic energies will be the same.
c) The crates will end up with the same kinetic energies.
d) Neither their momenta nor their kinetic energies will be the same.
Answer is NOT a or b

A lighter block (3 kg) and a heavier block (12 kg) sit on a frictionless surface. Both blocks are initially at rest. The same force of 6 N then pushes to the right on each block for a distance of 16 m. What are the initial kinetic energies of the blocks? What are the changes in kinetic energy of the blocks? What are the final kinetic energies of the blocks? What are the initial momenta of the blocks? What are...

The same horizontal force, of magnitude F, is applied to two different blocks, of mass m and 3m The blocks move on a frictionless surface and both blocks begin from rest. If each block moves the same distance as the force is applied, which one of the following sentences is true? O The heavier block acquires 3 times as much kinetic energy as the lighter block. The heavier block acquires 9 times as much kinetic energy as the lighter...

A spring of negligible mass is compressed between two masses on a frictionless table with sloping ramps at each end. The masses are released simultaneously. The masses have the same volume, but the density of M1 is greater than that of M2. Select the appropriate symbol for each statement: G (Greater than), L (Less than), or E (Equal to). (If the first two are 'greater than,' and the last four 'less than,' then enter GGLLLL). A) The duration of the...

Q: Compare the assumptions of physician-centered and
collaborative communication. How is the caregiver’s role different
in each model? How is the patient’s role different?
Answer: Physical-centered communication involves the specialists
taking control of the conversation. They decide on the topics of
discussion and when to end the process. The patient responds to the
issues raised by the caregiver and acts accordingly. On the other
hand, Collaborative communication involves a...
