Homework Statement Five dogs, each having a mass of 30kg, pull a 250kg sled horizontally across the snow (coefficient of kinetic friction = 0.14). How much force must each dog exert in order to move the sled at a constant velocity? Homework Equations Force of kinetic friction =...

Homework Statement The coefficient of sliding friction between two materials is 0.35. A 5.0 kg object made of one material is being pulled along a table made of another material. What is the force of friction? I'm fairly certain I solved the problem correctly, the thing is, I should be...

What do you mean? :confused:

Homework Statement An object that is thrown covers a distance of 8.59 m. If the angle at which it is thrown is 23 degrees, what is its initial velocity? Homework Equations 5 kinematic equations: a = (v2-v1)/t d=0.5(v1+v2)t d=v1t+0.5at^2 d=v2t-0.5at^2 v2^2=v1^2+2ad Equation for...

Thanks, I got the answer.
