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 8 above the horizontal, as shown in the figure. After the block is pulled through a distance of 1.50 m, its speed is 2.60 m/s, and 40.0 J of work has been done on it. F=45.0 N V=0 8 v=2.60 m/s -1.50 m a. What is the mass of the block? b. What is the angle e
