## Homework Statement

## 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 ?

ThanksThanks
