- A dart gun contains a spring of spring constant k = 16 N/m which is used to shoot a dart of mass m. The dart leaves the gun at a speed of v = 3.1 m/s after the spring is compressed 1 cm. what is the darts speed when it hits the floor (vf in m/s) if it is fired horizontally at a height of h = 2 m what angle in degree does the darts final velocity make with the horizontal?ture of Light A photon with a momentum of 60 keV/c, which is scattered at a quasi-free electron at rest at an angle of 120°, hits the surface of a molybdenum plate after the scattering process and gives ise to the emission of an electron (work function of 20 keV) there due to the photoelectric effect.
