Naveen claims that linear momentum is conserved in this simulation. (Ignore rotational momentum effects) A) Using data from the test A for Ball 1 or Ball 2, calculate the ball's momentum before and after the collision. The formula for momentum is p=mv.

Naveen claims that no net force is on the system, meaning that the momentum is conserved over time.

B) Using data from test B, verify Naveen's claim with evidence and calculations.

Ahair dryer is basically a duct in which a few layers of electric resistors are placed. a small fan pulls the air in and forces it through the resistors where it is heated. air enters a 1200 w hair dryer at 100 kpa and 22°c and leaves at 47°c. the cross-sectional area of the hair dryer at the exit is 60 cm2. neglecting the power consumed by the fan and the heat losses through the walls of the hair dryer, determine (a) the volume flow rate of air at the inlet and (b) the velocity of the air at the exit.
