An object is moving back and forth on the x-axis according to the equation x(t) = 3sin(20πt), t> 0, where x(t) is measured in cm and t in seconds. give decimal answers below. (a) how many complete back-and-forth motions (from the origin to the right, back to the origin, to the left and finally back to the origin) does the object make in one second? (b) what is t the first time that the object is at its farthest right? (c) at the time found in part (b), what is the object's velocity? (d) at the time found in part (b), what is the object's acceleration?

Describing the motion of an object can be difficult to do and using graphs make motion easier to understand. motion is a change in position measured by distance and time. speed tells us the rate at which an object moves. speed graphs are distance-time graphs; sometimes people label them as position-time graphs as well. time is plotted on the x-axis and distance or position on the y-axis of a line graph. a distance-time graph tells us how far an object has moved with time. • the steeper the graph, the faster the motion. • a horizontal line means the object is not changing its position. it is not moving, and it is at rest. • a downward sloping line means the object is returning to the start. use the text and the graphs above to choose all of the correct answers concerning speed? in both graphs, speed will be measured in meters/second. in graph a, the object travelled a distance of 40 meters in 4 seconds the total distance travelled by the object in graph b is greater than the object in graph a. in graph b, the object is at rest for 5 seconds. the object in graph b was moving at a greater speed than the object in graph a

Consider an object moving in the plane whose location at time t seconds is given by the parametric equations: x(t)=4cos(πt) y(t)=3sin(πt). assume the distance units in the plane are meters. (a) the object is moving around an ellipse (as in the previous problem) with equation: x2 a2 + y2 b2 =

The location p(t) of an object moving in the xy-plane at time t seconds is given by the equations p(t)=(x(t),y( where x(t)=a +3t and y(t)=b +8t, a,b are constants and distances are measured in units of meters. the equations x(t), y(t) describe linear parametrized motion; see section 10.1 of the textbook for review. (h) the line along which the object is moving in the plane has the equation: y=+ (i) let d(t) be the distance the object has traveled after t seconds. the formula for d(t) is: (j) the instantaneous rate of change of d(t) at time t is:
