Suppose the coefficient of static friction between the road and the tires on a car is 0.60 and the car has no negative lift. What speed will put the car on the verge of sliding as it rounds a level curve of 36.3 m radius?
Just as you had done in your lab, imagine that you have a solid uniform disk (same as a uniform cylinder) with a string wound around its rim. What is the angular acceleration of the disk
Evaluate the magnitude of the acceleration of each mass. What percentage of error in would be made if the moment of inertia of the pulley were ignored? Ignore friction in the pulley bearings.
Atomic physicists usually ignore the effect of gravity within an atom. To see why, we may calculate and compare the magnitude of the ratio of the electrical force, What is the magnitude of the electrical force
A 1050kg car carrying four 78kg people travels over a rough "washboard" dirt road with corrugations 4m apart which causes car to bounce on its spring suspension.
As the fragment falls through the atmosphere, it is heated and some of the material is vaporized. Explain how you could determine the composition of this hot vaporized material from the light it emits.
Assuming that air resistance is simply a constant 95 N force on the person during the fall, evalute the person’s velocity just before hitting the net.
Three 17--long rods form an equilateral triangle. Two of the rods are charged to + 16 , the third to - 16 . What is the electric field strength in the middle of the triangle
A mass m= 200kg hangs from a horizontal ceiling by two cables, one of length 3.0m and the other 4.0 m ; What is the tension in each cable
Stone with a mass of 0.800 {rm kg} is attached to one end of a string 0.900 {rm m} long. The string will break if its tension exceeds 65.0 {rm N}. The stone is whirled in a horizontal circle on a frictionless tabletop; the other end of the string rem..
The thermal expansion coefficient of copper is about 1.7x10-5 / oC. A copper cable has a length of 20 m early in the morning, when the temperature is 15 oC. What is the change in it's length (Lnew-Lold) at noon, when the temperature is 25 oC?
