    What is the center of mass of a pyramid?

    the work? As to part B of this problem. Would the work be the integral of mgh? where after you integrate it would be mg*h^2/2 ?

    Engine Performance(Finding Power)

    I ended up getting it. I used the equation P=W/t, where work = change in kinetic energy. Thanks for the help.

    Engine Performance(Finding Power)

    Ok, here is the problem: A car manufactuerer claims that their car can accelerate from rest to 101 km/hr in 5.6 seconds. The car's mass is 840 kg. Assuming that this performance is achieved at constant power, determine the power developed by the car's engine. Part B) What is the car's speed...

    Maximizing Speed on a Curved Road with Changing Friction Coefficient

    equation How did you get mu(v^2/r)=g? It seems like it should be Ff=ma which would be mu*m*g=m(v^2/r). Btw, are you in physics 152 at Purdue?
