Can someone help me with my assignment. (Will Mark Brainliest). I posted a picture of part 1. ( Part 2) Directions: Use the KE and GPE equations to solve for speed or height depending on the situation. Question 1) A 1,000-kg car has 50,000 joules of kinetic energy. What is its speed? Question 2) A 200-kg boulder has 39,200 joules of gravitational potential energy. What height is it at? Question 3) A 1-kg model airplane has 12.5 joules of kinetic energy and 98 joules of gravitational potential energy. What is its speed? What is its height? ( Need Help ASAP).

The graph below compares the rates of reaction of a burning candle and an exploding firework. comparing chemical reactions what can you conclude from the graph? the reaction that causes a firework to explode requires less energy to start, and occurs more rapidly than the reaction that causes a candle to burn. the reaction that causes a firework to explode requires less energy to start, and occurs less rapidly than the reaction that causes a candle to burn. the reaction that causes a firework to explode requires more energy to start, and occurs less rapidly than the reaction that causes a candle to burn. the reaction that causes a firework to explode requires more energy to start, and occurs more rapidly than the reaction that causes a candle to burn. mark this and return
