Energy, work and power — practice question
A block is fastened to one end of a light inextensible string. The string is inclined at $60^\circ$ above the horizontal and pulls the block along a horizontal floor in a straight line with acceleration $0.5\,\text{m s}^{-2}$. The tension in the string is $8\,\text{N}$. The block starts moving with speed $0.3\,\text{m s}^{-1}$. During the first $5\,\text{s}$ of the motion, find
