Young’s double-slit experiment is performed with 526 nm light and a distance of 2.00 m between the slits and the screen. The tenth interference minimum is observed 7.52 mm from the central maximum. Determine the spacing of the slits.

How much work must be done to stop a 920 kg car traveling at 107 km/h? An 81 g arrow is fired from a bow whose string exerts an average force of 95 N on the arrow over a distance of 75 cm. What is the speed of the arrow as it leaves the bow? At an accident scene on a level road, investigators measure a car’s skid mark to be 68 m long. It was a rainy day and the coefficient of friction was estimated to be 0.38. Use these data to determine the speed of the car when the driver slammed on (and locked) the brakes A spring has a spring constant, k, of 435 N/m. How much must this spring be stretched to store 21 J of potential energy?

A 46 kg pole vaulter running at 11 m/s vaults over the bar. Her speed when she is above the bar is 0.7 m/s. The acceleration of gravity is 9.8 m/s2 . Find her altitude as she crosses the bar. Neglect air resistance, as well as any energy absorbed by the pole. Answer in units of m.

I attach my homework, this is 3 time I send it.

For the first 12.0 {rm m} the floor is frictionless, and for the next 12.0 {rm m} the coefficient of friction is 0.16.

A space station is constructed in the shape of a wheel 25 in diameter, with essentially all of its 5.1×105 mass at the rim. Once the station is completed, it is set rotating at a rate that requires an object at the rim to have radial acceleration , thereby simulating Earth’s surface gravity. This is accomplished using two small rockets, each with 150 thrust, that are mounted on the rim of the station.How long will it take to reach the desired spin rate?
