Problem

A 1.0 kg1.0\,\text{kg} firework shell is initially at rest on a frictionless horizontal surface. It explodes into three fragments. Immediately after the explosion: • Fragment A (0.20 kg0.20\,\text{kg}) moves at 4.0 m/s4.0\,\text{m/s} due east. • Fragment B (0.30 kg0.30\,\text{kg}) moves at 3.0 m/s3.0\,\text{m/s} directed 30∘30^{\circ} north of west. Determine the magnitude and compass direction of the velocity of Fragment C (0.50 kg0.50\,\text{kg}).
