In summary, two large crates with masses 640 kg and 490 kg are connected by a spring and propelled on a frictionless floor by an applied force. The spring compresses 5.1 cm and the applied force and forces acting on the smaller mass can be determined using the equation F = ma. The acceleration of each mass can be found by dividing the applied force by the total mass. For the smaller mass, the restoring force of the spring can be calculated using the equation F = kx, and the acceleration can be solved for in terms of the applied force.

Two large crates, with masses 640 kg and 490 kg, are connected by a stiff, massless spring(k= 8.1 kN/m) and propelled along an essentially frictionless, level factory floor by a force applied horizontally to the more massive crate. If the spring compresses 5.1 cm from its equilibrium length, what is the applied force?

What force does the spring exert? What forces act on the smaller mass? What's its acceleration?

Determine acceleration of the two masses (Applied force/Total mass). This will be the acceleration of each mass. Consider the smaller mass alone. Force acting on it is due to the restoring force of the spring, which is equal to kx. Write equation : Force = mass x acceleration for the smaller mass (acceleration a is in terms of the applied force F). Solve for F.
