A block of mass M=10kg is acted on by an applied forceF1 directed at 30degrees above the horizontal. The blockslides on a surface with μk=0.20 and starting fromrest, achieves a speed of 4m/s after sliding a distance d=2m. Whatis the acceleration of the block? What is the magnitude ofF1? If the force F1, is now removed, how much farther will the block slide?
