A train is traveling up a 5.0 degrees incline at a speed of 2.65 m/s when the last car breaks free and begins to coast without friction.
a.) How long does it take for the last car to come to rest momentarily?
b.) How far did the last car travel before momentarily coming to rest?
Astronomers determine that a nearby galaxy is moving toward our galaxy at a speed of 720.0 km/s with respect to the Earth, what was the wavelength emitted by the star
A curve of radius 50 m is banked for the design speed of 100 km/h. If the coefficient of static friction is 0.60 (wet pavement), at what range of speeds can a car safely create the curve.
How far apart are an object and an image formed by a 75-cm focal-length converging lens if the image is 2.64 X larger than object and is real.
