    How can we find the center of mass of a solid cone?

    should we also take a height of every hollow cone as "dh" ?

    How can we find the center of mass of a solid cone?

    is this method even possible? anyways here is my attempt Step1) y= 2H/3 ( H is the height of the cone) step 2) we take the density (ρ)= 3M/π R2 H. The problem i am facing is to Find "dm"

    Kinematics of a kicked football

    according to me the answer should be "G". Use equation of trajectory and put x=32.3 v=22.2 and theta=49.4 after plugging in the values you should get some "y" after that just subtract the height of the goal post.

    Why can't we do this by using radius of curvature?

    I have tried this question thrice. and for 3 days. I will try to explain My attempts as best as i can Attempt-1--> This is fairly basic. I found X(t) and Y(t) in polar form and put them in the equation of circle. After that diffrentiated both sides with respect to "x" however the answer came...
