3.4kg rock starts at 25 cm on a plane with a 33degree angle. upon reaching the bottom the box slides along the horizontal. friction coeff is
.19. how far does the box slide on the horizontal before coming to a rest?
ok i need to use .5MVi2 + MGy1 = .5MVf2 + MGy2 + Ffrd
first i need to find the velocity of the box as it hits the end of the incline. i also need the length of the incline.
i have Y1=.025 meters
Vf=0
Vi=0
M=3.4kg
g=9.8
theta=33
fr=.19
i keep getting 4.3 meters but its wrong
