A block of mass m slides up the inclined plane with an initial speed v₁. H m a. If the incline is frictionless, find the maximum height H reached by the block. b. If the incline is rough with friction coefficient u, find the maximum height H reached by the block. C. A thin hoop of mass m and radius R replaced the block. If the incline is frictionless, find the maximum height H reached by the hoop. d. A thin hoop of mass m and radius R replaced the block. If the incline is rough with friction coefficient u, find the maximum height H reached by the hoop.
