WebSo the normal force also does no work on the trashcan. This makes sense because forces that are perpendicular to the motion can never do any work on that object. So that's how you can find the work done by individual forces. And if we wanted to know the net work done on this trashcan, we could just add up the work done by each individual force. WebTrigonometry. Trigonometry questions and answers. Find the amount of work done pulling an object horizontally 30At if a force of 60tb is directed 30∘ above the harizontal. Give … Web4 nov. 2024 · The work done on the ball by the external force is − m g h with the negative sign there because the direction of the external force (downward) is in the opposite direction to its displacement (upward). So − E i n i t i a l = − m g h ⇒ E i n i t i a l = m g h. During this time the acceleration of the ball a = g is downwards. flowers for delivery in cedarburg wi
