a slit of width 0.010 mm has a light of frequency 5.0 x 10^14 Hz passing through it onto a screen 60 cm away. how wide is the central maximum

Using the work energy theorem. what is the velocity of a 850kg car after starting at rest when 13,000j of work is done to it.

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
