A spring with an elastic constant of 26 N/m, and want it to oscillate once every 0.75 seconds. What mass would you need to attatch to the spring?
A diffraction grating 22.0mm wide has 6000 rulings. Light of wavelength 592nm is incident perpendicular on the grating. What is the largest value of theta at which maxima appear on a distant viewing screen
An object, at the top of a very tall building, is released from rest and falls freely due to gravity. Neglect air resistance and compute distance covered by the object between times t1 = 5.5 s and t2 = 7.9 s after it is released.
One way to measure on another planet or moon by remote sensing is to measure how long it takes an object to fall a given distance. A lander vehicle on a distant planet records the fact that it takes 3.17 for a ball to fall freely 11.26.
