13. How much work is done on a 10 N block that is lifted 5 meters off the ground by a pulley? Type a response

When lifting a block against gravity, the work done is calculated using the formula: Work = Force × Distance. In this scenario, you have a 10 N force (the weight of the block) and a distance of 5 meters. So, Work = 10 N × 5 m = 50 Joules. That means you’ve put in some serious effort—feels great knowing you’ve done 50 Joules of work to lift that block! It's also interesting to note that when you're using a pulley, it helps reduce the amount of force needed to lift heavy objects. This makes the process easier on your muscles while still requiring the same amount of work to be done, thanks to the magical manipulation of force direction. So, whether it’s a simple block or the grand pyramids, pulleys are your trusty sidekicks in lifting!
