Document Summary
Answer: assumptions: the density of air is constant throughout the room, properties: the density of air is given to be = 1. 16 kg/m3. The mass of the air in the room is. Air: a 3-kg rock is thrown upward with a force of 200 n at a location where the local gravitational acceleration is 9. 79 m/s2. Determine the acceleration of the rock, in m/s2. Answer: the weight of the rock is: N: then the net force that acts on the rock is: From the newton"s second law, the acceleration of the rock becomes a. 2m/s: while solving a problem, a person ends up with the equation e = 25 kj + 7 kj/kg at some stage. Here e is the total energy and has the unit of kilojoules. Determine how to correct the error and discuss what may have caused it. The two terms on the right-hand side of the equation.
