What is the change in kinetic energy of the cart : A 17.5 kg cart is moving with a velocity of 7.65 m/s down a level hallway. A constant force of -10.0 N acts on the cart, and its velocity becomes 3.20 m/s. Assume that air resistance is negligible.
What is the velocity and direction of the third piece : An m = 6.60-kg clay ball is thrown directly against a perpendicular brick wall at a velocity of 22.0 m/s and shatters into three pieces, which all fly backward, as shown in the figure. The wall exerts a force on the ball of 2630 N for 0.110 s.
Mass-photons-traveling at speed of light-have momentum : Although they don’t have mass, photons—traveling at the speed of light—have momentum. Space travel experts have thought of capitalizing on this fact by constructing solar sails—large sheets of material that would work by reflecting photons
Find final speed of the train if there had been no friction : In the 1950s, an experimental train that had a mass of 2.00 104 kg was powered across a level track by a jet engine that produced a thrust of 5.30 105 N for a distance of 509 m. Assume that air resistance is negligible.

A different wheatstone bridge has a sensitivity : A different Wheatstone bridge has a sensitivity of 2.6 mV/O. What will be the approximate output voltage difference when ?Rx = 50 O? Express the answer in millivolts.
Piston-cylinder device has nitrogen gas : Piston-cylinder device has nitrogen gas at 160 kPa and 158oC. The 23-cm diameter piston initially pushes against a set of stops. Before the piston starts moving down, 2 kJ of heat is transferred from the gas to the surroundings. The cooling contin..
A large tank is divided into two parts by a partition : A large tank is divided into two parts by a partition. The first part contains 5 kg of refrigrtant-134a at 80oC, 900 kPa. The other part contains 3 kg of refrigerant-134a at -2oC with a vapor mass fraction of 46 percent.
