Would doubling the kinetic energy of an object have any effect on the momentum?

I understand what you mean: w = fd d = w / f but I am unaware of how I know how much energy there is from the velocity. edit: would you substitue w for Ek, which would be 1/2mf^2 - 1/2mvi^2?

Homework Statement A football player weighing 71 kg running at 2.1 m/s sacks a stationary quarterback who weighs 52 kg. How far will the two move after the collision if the coefficient of friction between the cleats and ground is 0.052. Homework Equations m1v1' + m2v2' = mv'1 uk = Fk...

Car tires seem to bounce very well however they are easily unbalanced and tend to tip over very easy. If you were to connect say 2 or 3 similar tires together and then dropped it, it should prevent the tires from tipping over and stop bouncing. This will however make the mass significantly...

Since they are equal and opposite though, would that imply that they are balanced forces?

Newtons third law states that for every force there is an equal an opposite force. This doesn't mean that these forces are balanced though? Things like cars or people walking can still accelerate so these forces can't be balanced?

Yeah, the distance should be 2 m, not -2 m for part a. I am not sure if I am following you for part b though. I understand how his velocity should be less than when he started. His vertical velcoity at maximum height would be 0 and his horizontal velocity would still be the same, which is...

Homework Statement A circus clown is fired from a cannon into a net that is situated 2.0 m above the cannon at some distance from it. The cannon is elevated at 50 degrees to the horionztal and the clown's speed at lunch if 15 m/s. (a) Find the horizontal distance from the cannon where the...

Hey guys I am looking for some ideas of projects to do for a physics class. It is for the last year of high school. I am open to all kinds of ideas, feel free to share them :)
