Physics Problem. Please HELP!! 1. The problem statement, all variables and given/known data Two blocks on a frictionless horizontal surface are connected by a light strong. Gravity is 9.8. Diagram: 4.13kg--T--21.2kg--->50.8N a. What is the tension in the string between the blocks? Answer in units of N. b. If the surface were frictional, and the coefficient of kinetic friction between each block and the surface is 0.0958, what would be the new acceleration? Answer in units of m/s^2 c. What would be the new tension in the string between the blocks? Answer in units of N 2. Relevant equations 3. The attempt at a solution I thought that because it was frictionless for a. the tension would just be 50.8 again, but it was wrong...(im entering answers online) grrr...I'm completely lost!!!! Help!? anyone?
