A roller coaster has 800,000 Joules of kinetic energy and is moving with a speed of 40 m's What is the mass of the roller coaster ing?
As boe in the number for your answer, not the units
The formula for kinetic energy is
The formula for potential energy is
velocidorspeed inms
8 - 10m this really 9.8 m son earth but we will use 10 for simplicity

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)
