Everybody loves a good hero. But, are they realistic? Some of our favorite crusaders  Batman, Link, Green Arrow  use grappling hooks to get around. I wonder if they’d work like in the games and movies. Let’s say Batman is trying to get into Arkham Asylum to teach some no goodnicks what he thinks of this whole “rehabilitation” thing. He needs to get two floors up, which is about 6.6 m. And, like in the movies, he needs to rocket up that distance, let’s say at about 6 m/s. The average man weighs 70 kg, but Batman is pretty buff, so we’ll make it 75 kg. We can calculate the work needed to be (.5)mv^2 + mgh, which here equals 6205.95 J. We also know v = d/t, so that means t = d/v = 1.1 s. And, power = W/t = 5641.77 W. It’s pretty safe to say a handheld motor like the ones we see in the media couldn’t make over 5.5 kW of pull. A mounted artillery grappling gun could, and are used by the US special forces for stealth missions. However, until our technology evolves a bit more, Batman will just have to learn to actually fly.

Listen to this. lets talk about work. Work is not only equal to force times distance, but is also equivalent to the change in kinetic energy. For instance, if a car of mass m is traveling 10 m/s and comes to a stop in 15 m, its very easy to find the work. Work=Change in Ke=((1/2)m(10)^2) ((1/2)m(0)^2)=50m This means that the breaks in this car must do 50m j of work to stop the car.

Hello! I'm using the "AP Physics Essentials: 1" book to study for my Work, Power, and Energy exam (chapter 5.) I need clarification on question 5.10; how do we decide on the equation to use? I'm so lost on how to make that determination. Thanks!
