022 (part 1 of 4) 10.0 points a ball is thrown vertically upward with a speed of 24.5 m/s. how high does it rise? the acceleration due to gravity is 9.8 m/s 2 . answer in units of m.
023 (part 2 of 4) 10.0 points how long does it take to reach its highest point? answer in units of s.
024 (part 3 of 4) 10.0 points how long does it take the ball to hit the ground after it reaches its highest point? answer in units of s.
025 (part 4 of 4) 10.0 points what is its velocity when it returns to the level from which it started? answer in units of m/s.
026 10.0 points an object is released from rest on a planet that has no atmosphere. the object falls freely for 4.88 m in the first second. what is the magnitude of the acceleration due to gravity on the planet? answer in units of m/s 2 .

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)
