Aball hits the ground at a with a velocity vo of 6 m/s at
anangle of 60 degrees with the horozontal. knowing that e =
0.6between the ball and the ground and that after rebounding the
ballreaches point b with a horizontal velocity, determine (a)
thedistances h and d, (b) the velocity of the ball as it
reachesb.

Atank with constant volume contains 2.27 kg of a mixture of water phases (liquid-vapor). in the initial state the temperature and the quality are 127 °c and 0.6, respectively. the mixture is heated until the temperature of 160 oc is reached. illustrate the process in a t-v diagram. then, determine (1) the mass of the vapor in kg at the initial state, (2) the final pressure in kpa.
