- A 7 kg point mass is at coordinates (5 m, 5 m), a 4 kg mass is at (-5,7) and a 5kg mass is at (x,y) of (4,-7). Find the moment of inertia about the x axis. Find Iz = __________ kg-m2The ball has a mass of 1 kg and is confined to move along the smooth vertical slot due to the rotation of the smooth arm OA. The rod is rotating with a constant angular velocityd slot at any instant. Which one of the following is (are ) incorrect answers ? =2 rad/s. Assume the ball contacts only one side of the ion e-2 rads Select one or more: There is only one contact force on the ball that is acting perpendicular to the rod. There are two contact forces on the ball: one is acting perpendicular to the wall, and the other is perpendicular to the rod. The path of the ball is given by r 0.5 sec 0. The acceleration along the 0 increasing direction is a, tan 6 sec 00 The normal reaction to the ball by the rod is given by the equation N gcos+ a, whiere ap s the acceleration along the 6 increasing direction.A 3.0-kg mass slides on a frictionless horizontal surface with a speed of 3.0 m / s when it collides with a 1.0-kg mass initially at rest as shown in the figure.
