Two identical trucks each of mass M (excluding sacks of rice) move on national highways with speeds v1 and v2 towards each other. When they meet each other, a sack of rice of mass m is thrown from one truck to the other and an identical sack of rice is thrown from the second to the first. Calculate their velocities v1? and v2? after the exchange of sacks, given m = 50 kg, M = 200 kg, v1 = 50 m/s and v2= 200 m/s. Friction of the road may be neglected.
