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

**Physics**

the exact formula for this should be in your text book

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

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 ...
