Question

You attach a cord to the a block of mass m and use it to move the block to the final height h. You can do this either by lifting the block vertically or by sliding it up a frictionless ramp of height h. which of the following statement is true a. the magnitude of the tension in the cord is greater using the ramp b. the magnitude of the tension in the cord is the same either case c. the work done on the block by tension force is the same both cases d. the work done on the block by tension force is less for the ramp e. the work done by the gravitational force is smaller for the ramp.
