SUMMARY
The discussion focuses on calculating the average force opposing a proton's motion as it passes through a metal film. A proton with a mass of 1.67 x 10-27 kg and an initial speed of 5.0 x 106 m/s emerges from the film at a speed of 2.0 x 106 m/s after traveling through a thickness of 0.010 mm. The participants confirm the use of Newton's second law (F=ma) and the kinematic equation Vf2 = Vi2 + 2ax to find the average force. The solution involves calculating acceleration and then applying it to determine the force.
PREREQUISITES
- Understanding of Newton's second law (F=ma)
