Notice that the work is doubled either by lifting twice the weight the same distance or by lifting the same weight twice the distance. If we want to get a better estimate of distance travelled, we can split up the time interval into sub-intervals and pretend that velocity is constant on each sub-interval. AP Calculus Worksheet: Rectilinear Motion 1. However, the distance traveled is irrespective of direction, so we must remember to take the absolute value of the velocity first. Suppose an object is moving in a straight line, and let its velocity at time t be given by the function f ( t ). If the graph dips below the x-axis, you’ll need to integrate two or more parts of the graph and add the absolute values.

EXAMPLE 3 Calculating Total Distance Traveled Find the total distance traveled by the particle in Example 1. (b) Is the speed of the particle increasing at time t = 3? Give a reason for your answer. will have a horizontal tangent? (7 Points) 15) Find the slope of the tangent line to the curve. Find the total distance the particle has traveled between 0 and 8 seconds. (c) Find the acceleration of the particle at time t. (c) Find dy dx as a function of x. EDIT - I made a slight mistake the first time I posted this. Summary Distance Traveled This final application, that of finding the distance traveled by an object given its velocity at each moment, follows directly from the fundamental theorem of calculus. 0 ≤ t ≤ 7. Does this mean that a particle sliding on a cycloid is equivalent to a simple harmonic oscillator? Find out by expressing the motion as an equation where the distance variable from the origin is s measured along the curve. Distance and displacement are different quantities, but they are related. A particle’s velocity is represented by the graph below.
