Difficult: Block sliding up moving ramp 1. The problem statement, all variables and given/known data A block of mass m with initial velocity of v0 slides up up a ramp of angle [tex]\theta[/tex] and mass M that is not pinned to the ground. It doesn't reach the top before sliding back down. What is the highest point that the block reaches in terms on [tex]\theta[/tex], v0, and m. There is no friction between any surfaces. 2. Relevant equations [tex]p = mv[/tex] [tex]J=Ft[/tex] [tex]E_i=E_f[/tex] 3. The attempt at a solution [tex]E_i=E_f[/tex] [tex].5mv_0^2=.5Mv_r^2+mgh[/tex] [tex]p_i=p_f+J[/tex] [tex]mv_0= Mv_r+Ft[/tex]<-at top height [tex]F=mg+mgcos\theta[/tex]<-from standard block on ramp problems Is this correct?
