A block rests on a horizontal, frictionless surface. A string is attached to the block, and is pulled with a force of 45.0 N at an angle above the horizontal, as shown in Figure 7-23. After the block is pulled through a distance of 1.50 m its speed is v = 2.90 m/s, and 50.0 J of work has been done on it.
