A man is driving his car with speed 45.0 mi/h on a horizontal stretch of road.(a)When the road is wet, the coefficient of static friction between the road and the tires is 0.101. Find the minimum stopping distance (in m).m(b)When the road is dry,μs = 0.597.Find the minimum stopping distance (in m).

The current in a hair dryer measures 11 amps. the resistance of the hair dryer is 12 ohms. what is the voltage?unit:

Wo small variable-thrust jets are actuated to keep the spacecraft angular velocity about the z-axis constant at ? 0 = 1.16 rad/s as the two telescoping booms are extended from r1 = 1.18 m to r2 = 4.69 m at a constant rate over a period of 124 seconds. the small 19-kg experiment modules at the ends of the booms may be treated as particles, and the mass of the rigid booms is negligible. determine the necessary thrust t for each jet as a function of time where t = 0 is the time when the telescoping action is begun. after you have the general expression for t, answer the questions. show work.
