The 0.14 kg tree topper is accidentally knocked off of a Christmas tree giving it an initial speed of 15 m/s . The tree topper ornament was initially at a height of 2.2 m above the ground and as falls it bumps into the leaves and the branches of the tree. If the work done by friction of the leaves and branches, on the ornamentis 3.6what is the speed of the ornament right as it hits the floor ?
