- 1a. A student does 125.0 J of work lifting a 12.0 kg book. How high was the book lifted? 1b.The book from problem 1 is then allowed to slide down a straight ramp which makesa 26.0o angle above the horizontal, and the book reaches its original position at the endof this ramp. How fast would it be going if there was no friction?3) The meaning of the word "WORK" is quite different in physics from its everyday usage. Give an example of an action a person could do that "feels like work" but that does not involve any work as we've defined in this chapter. Support your reasoning with equations/data.No calc. Please follow required steps to better understand.
- 1.3 A dog pulls a cart with a constant force of 50N. How much work is done by the dog to move the 200 m cart if the handle forms an angle of 20° with the ground?Please do itIndicate whether the statement is true or false. If false, change the identified word or phrase to make the statement true. 9. No work can be done when the force of an object is perpendicular to the displacement of an object 10. As the velocity of an object halves , the kinetic energy halves.
