Physics question (mass at rest raised to height by force. What is velocity)?

Click For Summary
SUMMARY

The discussion centers on calculating the velocity of a mass at rest raised to a height using the work-energy theorem. Given parameters include a mass (m) of 10 kg, a height (h) of 12 m, and a force (F) of 200 N. The relevant equations include F = ma and the work-energy theorem expressed as F Δy = ΔK.E. + ΔG.P.E., where G.P.E. is defined as mgy and K.E. as 1/2 mv². The solution emphasizes the need for clarity in problem statements for effective resolution.

PREREQUISITES
  • Understanding of Newton's Second Law (F = ma)
  • Familiarity with the work-energy theorem
  • Knowledge of gravitational potential energy (G.P.E.)
  • Basic concepts of kinetic energy (K.E.)
NEXT STEPS
  • Study the work-energy theorem in detail
  • Learn how to derive kinetic energy equations
  • Explore gravitational potential energy calculations
  • Practice problems involving forces and motion
USEFUL FOR

Students studying physics, particularly those tackling mechanics and energy concepts, as well as educators looking for clear explanations of the work-energy theorem.

Homework Statement


m=10k
h=12m
F=200N

Homework Equations


a=v/t
F=ma


The Attempt at a Solution


I cannot find the remaining equations to completely work the problem.
 
Physics news on Phys.org
I recommend using the work energy theorem. For a constant force it will be

[tex]F \Delta y = \Delta K.E. + \Delta G.P.E[/tex]

where G.P.E. is gravitational potential energy and is equal to [tex]mgy[/tex] . And K.E. is kinetic energy and is equal to [tex]1/2 mv^2[/tex]

(And please try next time to explain the problem a bit more clearly) :wink:
