Math 111 - Notes
Antjderjyatjyes A function F is an antiderivative of f if F'(x) = f(x). Rules:
fdx=x+C
fkf(x)dx = kff(x)dx
J[f(x) ± g(x)~x = f f(x)dx ± f g(x)dx
x n+1
f xndx = - +C if nil'! 1; and, fX-1dx = lnlxt + C n+l
Acceleratjon, Velocity, Speed
Relationships: aCt) = viet) = s"(x) or h"(t) ~ (t) ~ 5 (t)
For free falling bodies: aCt) = -32, since acceleration due to gravity is a constant, and the following: vet) = -32t + C, and set) = -16t2 + C, t ... C2
"tips" ground: set) = 0 or h(t) = 0 initial velocity: v(O) or C, in above greatest height: vet) = 0 and solve for t
[this process maximizes set), stet) = vet)] dropped object: v(O) = 0 x feet above the ground initially: s(0) = x or C2 in above downward direction - negative upward direction - positive
Examples: 1. A ball is thrown vertically downward from the top of a 220 foot
building with an initial velocity of -22 ft/sec. Find: (a) its velocity after 3 seconds; (b) its velocity after falling 108 feet. (-1 18 ft/sec; -86 ft/sec)
2. A ball rolls down a hill. At time "t" (in seconds), its velocity is v(t) = -12t (in ft/sec). If the initial position of the ball is 96 feet from the bottom of the hill, find: (a) s(t); (b) aCt); (c) the ball's velocity when it reaches the bottom of the hill. (s(t) = -6t2 + 96; a(t) = -12; -48 ft/sec)
