5.3sin(8.4) make sure your calculator is in DEGo mode

Physics
the exact formula for this should be in your text book

Physics
not enough information to answer the question... acceleration? if there is no acceleration then: x-xo = vot x = 100m

calculus
use the quotient rule h(x)=ƒ(x)/g(x) h&prime(x)=[ƒ &prime (x)*g(x) - g&prime (x)*ƒ (x)]/g(x)2

physics
first 121 km/h (1000m/1km)(1h/3600s) = 33.6 m/s vf2 = vi2 + 2a(&Delta x) &Delta x is what we want to solve for, it tells us the distance which we will compress the barrier so it needs to be atleast that thick a is the max acceleration given which I don't really understand ...
