Final answer:
The hypothesis for this investigation is that the acceleration of the lead weight is directly proportional to the magnitude of the applied force. To test this, the student needs to measure the mass of the weight, apply a known force, and measure the acceleration.
Step-by-step explanation:
The hypothesis for this investigation would be that the acceleration of the lead weight is directly proportional to the magnitude of the applied force. In other words, if the student increases the force applied to the lead weight, they would expect to see an increase in its acceleration.
To test this hypothesis, the student would need to measure the mass of the lead weight using a balance. They would then apply a known force to the weight using a device like a spring scale or a force sensor. Finally, they would measure the acceleration of the weight using an accelerometer or by calculating it from the displacement and time taken.
By collecting this information for different magnitudes of applied force, the student can analyze the data to determine whether there is a linear relationship between force and acceleration.
