SUMMARY
The final speed of the sled with four bobsledders jumping in can be calculated using the principle of conservation of momentum. The initial mass of the sled is 210 kg, and each bobsledder weighs 63 kg, resulting in a total mass of 210 kg + (4 * 63 kg) = 462 kg. The initial speed of the sled is 3 m/s, and each bobsledder increases their speed by 2 m/s relative to the sled's current speed at intervals of 2 seconds. The final speed of the sled, once all bobsledders are in, is determined to be 5 m/s.
