Homework Equations
m*v^2 / 2 and k*x^2 / 2 and 0,5*m*v^2
The Attempt at a Solution
[/B]
in task a I got correct answer there v = 20 m/s
in task b I got wrong answer I got the distance = 0,76 m but I should be 32 m
here is my answer :
0,5*m*(sin(30)*v) - mu * m*g*cos(30) = m*g*h
h=0,38 m
sin (30) = h/L there L is the distance of the block when it goes up
L= h/sin(30) = 0,76
What I do wrong in task b ?
Thanks
