To find the velocity of an object falling freely from rest after 2 seconds, we can use the equations of motion. Here's a step-by-step solution: ### Step 1: Identify the known values - Initial velocity (u) = 0 m/s (since the object is falling from rest) - Acceleration due to gravity (a) = 9.8 m/s² - Time (t) = 2 s ### Step 2: Use the equation of motion ...
