can someone help me with vectors/physics

by flec, May 5, 2024, 6:07 PM

i need a detailed explanation on how to solve these kinds of problems

like explain like you would explain to a toddler that's how lost i am

like force normal, force gravity... force gravity is the only one i kind of understand

for these kinds of problems i was confused why the formula was 2000sin theta because i thought it should be solving sohcahtoa

its so hard to use vectors and stuff but apparently vectors are < x, y > where x is right and y is down

save me pls

ik for physics you have to understand this and not memorize it but it's so confusing to memorize

i think for 3 you have to like draw the graph so that the force of gravity is moving down and the force of normalup so the angle is like 18 deg w the surface??? so gravity works
