What is Heat Transfer in Iron and Brass Bars about?

Here are the steps to solve this problem: (a) Calculate the time elapsed from the instant block A leaves the table to the instant it strikes the floor. Given: Vertical distance fallen = 0.8 m Use the equation: v_f^2 = v_i^2 + 2*a*Δy Where: v_f = 0 m/s (final velocity is 0 at impact) v_i = horizontal velocity (which we will calculate in part b) a = acceleration due to gravity = -9.8 m/s^2 Δy = vertical distance fallen = 0.8 m Solve for time: 0 = v_i^2
