A30-g bullet is fired with a horizontal velocity of 450 m/s and becomes embedded in block b, which has a mass of 3 kg. after the impact, block b slides on 30-kg carrier c until it impacts the end of the carrier. knowing the impact between b and c is perfectly plastic and the coefficient of kinetic friction between b and c is 0.2, determine (a) the velocity of the bullet and b after the first impact, (b) the final velocity of the carrier.

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.
