Question
**Predict/Calculate Problem 7.20 - Enhanced with Feedback** **Problem Statement:** A 9.00 g bullet has a speed of 1.20 km/s. You may want to review (Page 204). **Part A** - **Question:** What is its kinetic energy in joules? - **Input Field:** \( K = \) ___ J - **Controls:** Submit, Request Answer **Part B** - **Question:** What is the bullet's kinetic energy if its speed is halved? - **Input Field:** \( K' = \) ___ J - **Controls:** Submit, Request Answer **Part C** - (No content displayed in the image for Part C) **Instructions for Completion:** Students should use the formula for kinetic energy: \[ K = \frac{1}{2}mv^2 \] where \( m \) is the mass in kilograms and \( v \) is the velocity in meters per second. Convert the given mass and speed into appropriate units before calculating.
