The cart shown above is made of a block of mass **m** and four solid rubber tires each of mass **m/4** and radius **r**. Each tire may be considered to be a disk. NOTE: A disk has rotational inertia where **M** is the mass and **L** is the radius of the disk. The cart is released from rest and rolls without slipping from the top of an inclined plane of height **h**. Express all algebraic answers in terms of the given quantities and fundamental constants. |
