    How many photons are produced when a 0.39 kg mass falls from a height of 2.9 m?

    Homework Statement A 0.39 kg mass falls from a height of 2.9 m. If all of the energy of this mass could be converted to visible light of wavelength 5.5 × 10^−7 m, how many photons would be produced? The acceleration of gravity is 9.8 m/s^2 . Planck’s constant is 6.63 × 10^−34 J · s, and the...

    Calculating Force Exerted by Fish on Fishing Reel

    Homework Statement A cylindrical fishing reel has a mass of 0.623 kg and a radius of 1.83 cm. A fric- tion clutch in the reel exerts a restraining torque of 0.614 N · m if a fish pulls on the line. The fisherman gets a bite, and the reel be- gins to spin with an angular acceleration of 49.1...
