16. A crate is sitting on the bed of a truck. The truck is moving at 21 km/h. Applying a constant braking force, the truck comes to a stop in 30. m. Find the minimum coefficient of friction between the crate and the bed of the truck if the crate does not slide. The crate has a mass of 10.0 kg.

An ideal otto cycle has a compression ratio of 8. at the beginning of the compression process, air is at 95 kpa and 27°c, and 750 kj/kg of heat is transferred to air during the constant-volume heat-addition process. assuming constant specific heats at room temperature, determine (a) the pressure and temperature at the end of the heat-addition process, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the cycle. (4390 kpa, 1730 k; 423 kj/kg; 56.4%; 534 kpa)
