Chapter 6, Problem 86PP

Referring to Example 6-13 Suppose that the mass on the frictionless tabletop has the value m₁ = 2.45 kg. (a) Find the value of m₂ that gives an acceleration of 2.85 m/s². (b) What is the corresponding tension, T, in the string? (c) Calculate the ratio Tm₂g and show that it is less than 1, as expected.
