Large cockroaches can run as fast as 1.50 m/s in short bursts. suppose that you turn on the light in a cheap motel and see a cockroach scurrying away from you in a straight line at a constant 1.50 m/s as you move toward it at 0.70 m/s. if you start 0.75 m behind it, what minimum constant acceleration would you need to catch up with the cockroach when it has traveled 1.30 m, just short of safety under a counter?

What are the three ways that an object can accelerate

Heterogeneous mixture with larger particles that never settle is

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.
