To solve the problem of calculating the retardation caused by the target when a bullet comes to rest after penetrating a distance of 10 cm, we can use the third equation of motion. Here’s the step-by-step solution: ### Step 1: Identify the known values - Initial velocity (U) = 20 m/s - Final velocity (V) = 0 m/s (since the bullet comes to rest) - Distance (S) = 10 cm = 0.1 m (convert cm to m) ### Step 2: Write the equation of motion ...
