A racing car has a mass of 1540 kg. What is its kinetic energy if it has a speed of 105 km/h? Assume that air resistance is negligible.
Question
Solution 1
Sure, let's solve this step by step.
Step 1: Convert the speed from km/h to m/s We know that 1 km = 1000 m and 1 hour = 3600 seconds. So, 105 km/h = 105 * 1000 / 3600 = 29.17 m/s.
Step 2: Use the formula for kinetic energy The formula for kinetic energy is KE = 1/2 * m * v^2, where m is the mass a Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
