1. The problem statement, all variables and given/known data A 5kg box is started at the top of a spiral slide at t=0 with a speed of 15m/s. The spiral has a radius, r=2m, and it's height is given by z=-.4Θ where z is in meters and Θ is in radians. The slide has a wall and a floor with a coe. of friction of .3 a) With no friction, what is the speed of mass when Θ=2pi? b)With no friction, what is the speed of the mass when t=.5s? c)With friction only between the floor and mass where does the mass stop and at what time? e)With friction only between the wall and the mass, what is the final speed of the mass? 2. Relevant equations z=-.4Θ W=ſFds W=1/2mv^2-1/2mv^2 3. The attempt at a solution Basically the polar coordinates throw me off. With out friction the only force is gravity. So can I just integrate to get my function which defines the position?
