SUMMARY

The discussion focuses on calculating the tension required to lift a 1400 kg car vertically with an acceleration of 0.50 m/s². The gravitational force (Fg) acting on the car is calculated as 13720 N, derived from the equation Fg = mg, where m is the mass and g is the acceleration due to gravity (9.81 m/s²). The net force (Fnet) needed for the upward acceleration is determined to be 700 N, leading to the conclusion that the total tension (T) in the rope must equal the sum of the gravitational force and the net force, resulting in T = Fg + Fnet = 14420 N.

PREREQUISITES
  • Understanding of Newton's Second Law (F=ma)
  • Knowledge of gravitational force calculation (Fg=mg)
  • Basic algebra for solving equations
  • Concept of net force in physics
NEXT STEPS
  • Study the principles of tension in ropes and cables
  • Learn about forces acting on objects in vertical motion
  • Explore real-world applications of Newton's laws in engineering
  • Investigate the effects of varying acceleration on tension calculations
USEFUL FOR

Students in physics, engineering professionals, and anyone interested in understanding the mechanics of forces and tension in lifting scenarios.

Homework Statement



How much tension must a rope withstand if it is used to accelerate a 1400 kg car vertically upward at 0.50 m/s2?


Homework Equations



Fg=mg F=ma

The Attempt at a Solution



So far i know Fg=13720 and the Fnet is 700 so I'm not sure but do i subtract 700 from 13720?

Would it make sense, physically, if the tension force were less than the gravitational force, as you are saying?
