SUMMARY
The total momentum of a system consisting of two connected rocks can be calculated using the formula for momentum, which is the product of mass and velocity. In this case, rock 1 has a mass of 0.2 kg and a velocity of 2 m/s upwards, while rock 2 has a mass of 0.35 kg and a velocity of 8.5 m/s horizontally. The total momentum is a vector sum of the individual momenta, resulting in a total momentum of 1.4 kg·m/s upwards and 2.975 kg·m/s in the +x direction. Therefore, the total momentum vector can be expressed as (2.975, 1.4) kg·m/s.
