A crate of mass 190 kg sits on a horizontal floor. The coefficient of static friction between the crate and the floor is 0.4, and the coefficient of kinetic friction is 0.36. You push the crate with a horizontal force of 500 N. What is the magnitude of the frictional force on the crate by the floor in this situation?[Use g = 9.81 m/s2]A small asteroid with a mass of 2000 kg moves near the Earth. At a particular instant the asteroid’s velocity is 〈 -1.30 x 104, 4.20 x 104, 0 〉 m/s, and its position with respect to the center of the center of the Earth is 〈 6.00 x 106, 10.00 x 106, 0 〉 m. The center of the Earth (mass = 5.97 x 1024 kg), is at the origin of the coordinate system. What is the (approximate) new momentum of the asteroid 1.50 x 103 seconds later?[Use: G = 6.67 x 10-11 Nm2 / kg2 ]

Two kilograms of air within a piston–cylinder assembly executes a carnot power cycle with maximum and minimum temperatures of 800 k and 300 k, respectively. the heat transfer to the air during the isothermal expansion is 60 kj. at the end of the isothermal expansion the volume is 0.4 m3. assume the ideal gas model for the air. determine the thermal efficiency, the volume at the beginning of the isothermal expansion, in m3, and the work during the adiabatic expansion, in kj.
