1. The problem statement, all variables and given/known data A Constant force of 75 N is applied horizontally to a block of ice on a horizontal plane. Friction is negligible. The block moves 12 m in the first 3 seconds. Find Mass in kg of block. 2. Relevant equations F=m*a m=F/a 3. The attempt at a solution Having trouble finding acceleration. I took 12m/3s to find the velocity, then velocity over time to give acceleration. I came up with 1.3 but this appeared to be incorrect. Help with the proper finding of acceleration would be great.
