A helicopter is moving horizontally to the right at aconstant velocity. The weight of the helicopter is W =53800N. The lift force L generated by the rotating blademakes an angele of 21 degrees with respect to the vertical.
a) what is the magnitude of the lift force?
b) Determine themagnitude of the aire resistance R that opposes the motion.
An object moves along the x axis according to the equation x = 3.85t2 ? 2.00t + 3.00, where x is in meters and t is in seconds. (a) Determine the average speed between t = 2.80 s and t = 4.60 s.
The coefficient of static friction between the block and table's surface is &mu s = 1/3. The mass of the block that is hanging down is n1 Kg. The tangent of the angle shown in the figure is tan & theta = n2. What is the minimum value of mass, n3 Kg t..
