1. The problem statement, all variables and given/known data My physics teacher - "You may like this question, its very structured" Calculate the distance a slate tile falls from a roof The roof is angled at an angle 30 degrees. mass of slate tile is 0.8kg The length of the roof is L=6m The height of the roof above the ground is h=10m The object will slide down the roof a distance L before it like launched as a projectile through the air until it reaches the ground. Coefficient of friction is assumed to be 0.5 g is for gravity Find d, the distance it reaches from the roof is d. 2. Relevant equations Friction force = Normal Contact force * coefficient of friction Resolving in Y Direction Normal Contact force = mass * g * cos (30) Resolving in X Direction ForceX= mass*g* sin(30) - Friction Force Now find acceleration of object sliding down roof using F=m*a a = ForceX / m Now find the velocity at the point the tile leaves the roof using v^2 = u^2 + 2*a*s a = ForceX/m s = Length of Roof = 6m v = ?? Now find the range distance the project will travel d_max = sqrt ( (v^2 / g) + 2 * (v^2 / g) * h ) 3. The attempt at a solution Please can you comment if my above logic and equations is good. I can plug the numbers in no problem.
