1. The problem statement, all variables and given/known data Figure 6-24 shows an initially stationary block of mass m on a floor. A force of magnitude 0.500mg is then applied at upward angle θ = 20°. What is the magnitude of the acceleration of the block across the floor if (a)μs = 0.620 and μk = 0.530 and (b)μs = 0.430 and μk = 0.340? 2. Relevant equations none 3. The attempt at a solution Problem seems unsolvable to me. No mass given, no force, etc. Have no idea what to do.
