Q5: A sled of mass m1 is moving on the frictionless air rail, and it is connected to a mass of m2= 50 g via a pulley. Sled starts its

motion with zero initial velocity at a point just adjacent to the photo gate. The time elapsed for the sled to move a distance of 0.2 m is measured as t= 0.5 s. The mass mi value of the slide is given in grams, which of the following options is correct? (Ignore the friction between the pulley and the string, as well as the masses of the string and mass hanger.)(g= 10 m/s^2) А) 353 g В) 163 g C) 253 g D) 263 g E) 200
