So would the total work formula be: $$ W_{total} = \Delta_{Ek} - W_{friction} $$
And from previous notes of mine I have that $$ W_{friction} = -\mu(m)(g)(d) $$
Sorry for asking so many questions, I'm really struggling to find questions online that mimic this problem.
Okay so I have rewritten my question using LaTeX (I think I'm using it properly). I realized that the sum of forces in the x direction equal ## (m)(a) ## . Is there anything going on in the y-component for acceleration? I believe that I only have to use the x component because the sled isn't...
Homework Statement
A boy pulls a sled (mass m=59.2 kg) along the ground using a force of magnitude F = 586 N inclined at an angle of θ=37.3° to the horizontal. There is friction between the sled and the ground with a coefficient of µk = 0.205. If the sled starts at rest, how much kinetic energy...
Homework Statement
A grenade is rolling due west at 0.954m/s along a floor when it explodes into three pieces of equal mass. The first piece moves at 3.6m/s, 20° [N of W]. The second travels at 5.8m/s, 62° [S of W]. Calculate the velocity of the third piece.Homework Equations
