On a banked race track, the smallest circular path on which cars can move has a radius of 109 m, while the largest has a radius 155 m, as the drawing illustrates. The height of the outer wall is 18 m.
(a) Find the smallest speed at which cars can move on this track without relying on friction
(b) Find the largest speed at which cars can move on this track without relying on friction.
What is the potential difference across capacitor. How much charge is on each place.
What is the linear charge density together the arc.
Two long, parallel conductors carry currents I1 = 3.10 A and I2 = 5.10 A, both directed into the plane of the computer screen. Find out the magnitude and direction of the resultant magnetic field at a point midway between the wires. (b) Find out the ..
A stunt man whose mass is 70kg swings from the end of a 4.50m long rope along the arc of a vertical circle. Assume that he starts from rest when the rope is horizontal, find the tensions in the rope that are required to make him follow his circula..
What must be the value of the putty mass m so that the amplitude after the collision is one-half the original amplitude.
The velocity component of the particle at x = 8.0 m is 2.8 m/s. Illustrate what is the acceleration component during this time interval?
An oil rig in the gulf is held at its designated drilling location by 3 tugboats. tugboat A oulls with 42000 N straight in the east direction. Tugboat B pulls at an angle of 50 degrees north of west. tugboat C pulls 25 degress west of south. draw ..
A 5.0 ? resistor is connected in series with another resistor and a 5.0 V battery. The current in the circuit is 0.70 A. Calculate the value of the unknown resistance
An automobile emits 20 lbs of CO2 per gallon of gasoline burned. If the U.S. burns 200 million of gallons of gasoline every year, how many billions of lbs of CO2 are emitted every year?
A certain fuel-efficient hybrid car gets gasoline mileage of 55.0 mpg (miles per gallon). If you are driving this car in Europe and want to compare its mileage with that of other European cars, express this mileage in km/l (liter).
A monatomic ideal gas expands on a linear process such that P=3V + P1 ( initial pressure.) P1 and V1 are the initial pressure and initial volume
A ball falls straight down onto a wedge that is sitting on frictionless ice. The ball has a mass of 3.11kg, and the wedge has a mass of 5.39 kg. The ball is moving the speed of v = 4.45m/s when it strikes the wedge, which is initially at rest.
