Finding Max Force Acting on a Moving Body Mass: A Challenge

Click For Summary
SUMMARY

The maximum force acting on a moving body mass of 1.6 kg can be determined using the calculated acceleration from the provided speed measurements: 7.00, 7.77, 8.89, 9.80, and 10.50 m/s. The correct approach involves calculating the instantaneous acceleration rather than the average acceleration, as the maximum force corresponds to the maximum acceleration. The force can be calculated using Newton's second law, F=ma, where 'a' is the maximum instantaneous acceleration derived from the speed data.

PREREQUISITES
  • Understanding of Newton's second law (F=ma)
  • Knowledge of kinematics and acceleration calculations
  • Familiarity with momentum concepts
  • Basic proficiency in calculus for instantaneous rates of change
NEXT STEPS
  • Calculate instantaneous acceleration from speed data using calculus
  • Explore the relationship between force and acceleration in dynamic systems
  • Study the concept of momentum and its implications in force calculations
  • Learn about graphical methods for analyzing motion and forces
USEFUL FOR

Physics students, engineers, and anyone interested in dynamics and force analysis in moving systems will benefit from this discussion.

The speed of a body mass m = 1.6 kg moving in a straight line varies smoothly. It is measured five times, at two second intervals. The values are 7.00, 7.77, 8.89, 9.80, and 10.50 (m/s). What is the maximum value of the force acting on the body?

I tried taking the average acceleration of the whole system and plugging it into F=ma but that didn't work. Then I tried finding the change in momentum but still unsuccessful.

why would the average be the maximum? :wink:
