Homework 12/2 Fall 2010 1. The function f ( x ) = 4 - x 2 measures weight in pounds (lbs) as a function of position x in feet. DeFne an accumulation function 1 T ( a ) = i a 0 f ( x ) dx Compute each of the following. Be sure to give correct units on each answer. (a) T (1) (b) T ( x ) (c) T ( x ) (d) T (1) 2. The acceleration of an object is given by 3 cos t m/s 2 , with t in seconds. DeFne an accumulation function 2 v ( x ) = i x 0 3 cos t dt Compute each of the following. Be sure to give correct units on each answer. (a) v ( - 2) (b) v ( x ) (c) v ( x ) (d) v ( - 2) 3. If F ( x ) = i x 0 (2 e u - u ) du , compute: (a) F (2) (b) F ( x ) (c) F ( x ) (d) F (2) 1 For those who are interested, f actually measures the weight of a load distributed across a beam sticking out from a wall. T is the resulting torque at the wall attachment point. 2
