Over the range of cylindrical parts manufactured on a computer-controlled lathe, the standard deviation of the diameters is .002 millimeter.
(a) What does Chebyshev's theorem tell us about the probability that a new part will be within .006 units of the mean for that run?
(b) If the 400...
thats what i thought but then i get stuck when i try to find the time it takes th suitcase to drop the 114 meters.
114 = 35.2t+.5(-9.8)t^2 is this the right equation?
Homework Statement
An airplane is flying with a velocity of 90.0m/s at an angle of 23 degrees w/ the horizontal. When the plane is 114 m directly above a dog that is standing on level ground, a suitcase drops out of the luggage compartment . How far from the dog will the suitcase land? You can...
what about the friction force is it up the incline or down the incline? I am confused about because usually the direction of friction force is opposite the direction of motion.
im also iffy on the net Torque. I am thinking that friction is the only force causing torque since the 45 N force is acting on the cylinders center.
am i right?
Homework Statement
A solid uniform cylinder with mass 5 kg is being pulled with a constant force of 45 Newtons up a 30 degree incline. The force is acting on the cylinders center and is parallel to the incline. What is its angular acceleration?
I have a good idea on how to do the problem...
