SUMMARY

The discussion centers on calculating the velocity of a 2.59 kg object that moves 56.9 cm under a force of 38 N. The key equation used is the work-energy principle, where work is defined as force multiplied by distance. The kinetic energy (KE) of the object is equal to the work done on it, which can be calculated as 38 N multiplied by 0.569 m, resulting in a KE of 21.582 Joules. The velocity can then be derived using the formula v = sqrt(2 * KE / mass), leading to a definitive calculation of the object's speed.

PREREQUISITES
  • Understanding of Newton's Second Law of Motion
  • Familiarity with the work-energy principle
  • Knowledge of kinetic energy calculations
  • Basic algebra for solving equations
NEXT STEPS

Homework Statement


Work is also measured in Joules. If a 2.59 kg object moves a distance of 56.9 cm as a result of 38N of foce. How fast is the object moving.


Homework Equations


?


The Attempt at a Solution


I started by trying to find the velocity using the square root of 2K(kinetic Energy) divided by the mass.

what did you get for KE in terms of the values provided?

idk i need help with this stuff in general
 


The question is a bit fuzzy IMO, but it starts with a statement about work.

Work is defined as force x distance.

If we can assume that all of that work went into propelling the object and none into say potential energy like moving it up a ramp:

the kinetic energy of the mass should be equal to that same quantity.
