1. During a medieval siege of a castle, the attacking army uses a trebuchet to hurl heavy stones at the castle walls. If the trebuchet launches the stones with a velocity of +9.0 m/s at an angle of 35.0° find the following: a) How long will each stone be in the air assuming the stones land at the same level as they are launched? Show all work.
9sin35=5.162 m/s
9cos35=7.37 m/s
5.16/9.8=0.527s
0.527time 2= 1.054s in the air.

b) What is the maximum height of the launched stones? Show all work.
0.5times 9.8^2times 0.527^2 = 13.337
1.365m is the maximum height.

c) What is the range (horizontal distance) that the stone will travel? Show all work
7.77m

d) What is the velocity of each stone as it hits the ground?

Acommercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at -35°c by rejecting waste heat to cooling water that enters the condenser at 18°c at a rate of 0.25 kg/s and leaves at 26°c. the refrigerant enters the condenser at 1.2 mpa and 50°c. if the compressor consumes 3.3 kw of power, determine (a) the mass flow rate of the refrigerant, (b) the refrigeration load, (c) the cop, and (d) the minimum power input to the compressor for the same refrigeration load.
