Determine la posición d en la que una bola arrojada hacia arriba y a la derecha, chocará con el plano inclinado que se muestra en la figura. La velocidad inicial de la bola es de 30 m/s dirigida como se indica con respecto a la horizontal.

Find the volume of the ellipsoid x^2+y^2+5z^2=36.

Plss anybody know how to do this? ? i need the answers from a through d

The 10-kg double wheel with radius of gyration of 125mm about o is connected to the spring of stiffness k = 600 n/m by a cord which is wrapped securely around the inner hub. if the wheel is released from rest on the incline with the spring stretched 225 mm, calculate the maximum velocity v of its center o during the ensuing motion. the wheel rolls without slipping
