Physics
A box having a weight of 8 lb is attached to a massless rod with length 2 feet. The initial speed of the box is 5 ft/s. Neglect friction and size of the box. If a moment of 10 ft-lb causes the box to increase its velocity from 5 ft/s to 10 ft/s, determine: rictly no di without written permissTON. a) The time it takes for the box to go from 5 ft/s to 10 ft/s b) The total work done during the time that the box goes from 5 ft/s to 10 ft/s c) The tension in the rod when the box has reached 10 ft/s
