Questions: 1. Using an energy transformation equation, show how energy is transformed for each of the following: a) A hotdog grilled on an outdoor BBQ b) A truck acceleration on a highway 2. A Truck does 3.2 kJ of work pulling horizontally on a car to move 1.8 m horizontally in the direction of the force. Calculate the magnitude of the force. 3. A store clerk moves a 4.4 kg box of soap at a constant velocity along a shelf by pushing it with a horizontal force of magnitude 8.1 N. The clerk does 5.9 J of work on the box. How far did the box move? 4. A 150 g text book is lifted from the floor to the shelf 2.0 m above. Calculate a) The force needed to lift the book without acceleration. b) The work done by the force on the book to lift it up to a shelf. 5.
