A1000 kilogram empty cart moving with a speed of 6.0 meters per second is about to collide with a stationary loaded cart having a total mass of 5000. kilograms. after the collision, the carts lock and move together. [assume friction is negligible.]
a) calculate the speed of the combined carts after the collision. [show all work, including the equation and substitution with units.]
b) calculate the kinetic energy of the combined carts after the collision. [show all work, including the equation and substitution with units.]
c) how does the kinetic energy of the combined carts after the collision compare to the kinetic energy of the carts before the collision?

In a stagnant pool of water, a crayfish may spend much of its time lying with one side of its carapace near the surface of the water. in this position, it will move the walking legs on that side in a rhythmic back-and-forth motion. explain the likely function of this behavior.

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.
