Summary:: I have done parts a-d but I can't seem to get e correct! A 6.10 kg block is pushed 9.00 m up a smooth 38.0 ∘ inclined plane by a horizontal force of 78.0 N . If the initial speed of the block is 3.20 m/s up the plane. a. Calculate the initial kinetic energy of the block. (found...

Oh shoot! Its supposed to be 4/3piR^3. So M= 2100 *(4/3 pi r^3) right? that should be right??

So I had M = 2100π R^3. Then I subbed that into the equation, for which the R got canceled and became R^2 and thus my result.

Summary:: Between the orbits of Mars and Jupiter, several thousand small objects called asteroids move in nearly circular orbits around the Sun. Consider an asteroid that is spherically shaped with radius r and density 2100 kg/m^3. a. You find yourself on the surface of this asteroid and throw...

This is the attempted work for this. I don't know how to find a and b from this... symmetric over the y-axis ⟹ ⟹ f(x) is an even quartic function ... f(x)=ax^4+bx^2+c y-intercept = -2 ⟹c=−2 f(x)=ax^4+bx^2−2 the local extrema info tells me two things... f(x)=0 at x=±2 f′(x)=4ax^3+2bx=0...

Find the equation of a quartic polynomial whose graph is symmetric about the y -axis and has local maxima at (−2,0) and (2,0) and a y -intercept of -2
