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(adsbygoogle = window.adsbygoogle || []).push({});

.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
