A small ball of mass 0.2 kg starts motion from rest at A by means of a compressed
spring with compression 0.5 m and spring constant k as shown in Fig.1 to move on a
rough horizontal plane
µk =0.4 and passes by point B to start motion inside a smooth tube until it reaches C
to move as a projectile and finally enters the shown net at D.
a) Study the motion of the ball as a projectile and determine VC.
b) Applying the principle of work and energy and deduced the value of the spring
constant k.

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
