## Homework Statement

If we have object with mass 10 kg traveling at starting velocity of 50 km/s and one force of resistance that is equal to v^2 of object's velocity how can we calculate distance and time in which that object travels until it gets to velocity of 10 km/s.

## Homework Equations

## The Attempt at a Solution

Kinetic energy at start - energy lost due to work of resistance = final kinetic energy

1/2 m v0^2 - ? = 1/2 m vf^2

As you can see I have trouble calculating work done by resistance. At start it will be starting velocity squared times distance but it changes every moment as velocity changes...
