similar triangles actually just think of it like this, the 120m/12ms^-1 means he takes a total of 10 seconds to travel. That 10 seconds is the same time it takes for the the 13ms^-1. Thus 13m*10sec=130metres.

frfr same

Nice cus i spent 3hrs watching william du doing questions on those 🤦‍♂️

no clue but ive always used the retractable for maths, i like a heavier pen but for english thats a disadvantage so thats why i swapped

looks good to me 👍

Another method will be using gravitational potential and centripetal force. We know that at the top of the loop, mv^2/r = mg, solving for v gives you v=sqrt(rg) We also know that the speed at that point of the ramp will be KE=U, 1/2mv^2final = mg change in h since Initial V =0 , solving for v...

check ur 2nd integration by parts again :),it was cot2x, but it changed to cotx

hv no clue, but thats what u get if u plug into https://www.integral-calculator.com/ (good website for integration solutions) but idk why it didnt work here

okie give me a sec i need to finish phys

u still need help?

How is mass defect, mass difference, energy and binding energy different? I'm kinda confused. Here's what I do know. Like I get the definitions, mass defect is difference in mass between nucleons and nucleus, whereas mass difference is difference between mass of products and reactants. binding...

i dont even use physics textbooks 😂 legit just follow my tutoring booklets they have like 99% of the content summarised
