A7.25 kg7.25 kg block is sent up a ramp inclined at an angle =28.5°θ=28.5° from the horizontal. it is given an initial velocity =15.0 m/sv0=15.0 m/s up the ramp. between the block and the ramp, the coefficient of kinetic friction is =0.326μk=0.326 and the coefficient of static friction is =0.593.μs=0.593. how far up the ramp in the direction along the ramp does the block go before it comes to a stop

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.
