Please answer part 1 and 2 carefully. Again, please and thank
you
Part 1:
The spring in the figure has a spring constant of 1000 N/m . It
is compressed 15.0 cm , then launches a 200 g block. The horizontal
surface is frictionless, but the block's coefficient of kinetic
friction on the incline is 0.180. (Figure 1)
What distance d does the block sail through the
air?
Express your answer with the appropriate
units.
