His speed at A is a constant up-80 ft/s He weighs 135 lb. Hint To determine the time derivatives necessary to compute the acceleration components ar and ae take the first and second time derivatives of r -600 cos 20) Determine the magnitude of the vertical reaction the seat of the plane exerts on the pilot when the plane is at A Express your answer to three significant figures and include the appropriate units. Then,for turther infomalion use +(re) to determine θ.

23. The programmer used three-point method to set up an accurate UF[3] on the part reference surface by sequentially recording points 1, 2, and 3 that are specified on the part reference surface for the three-points method in the robot system. If the programmer recorded three points used by the three-point method in the sequence of points 1, 3, 2 rather than point 1, 2, 3, then (a) the direction of x-axis is not changed (b) the direction of z-axis of UF[3] is changed (c) UF[3] setup is not accurate relative to the part reference surface (d) the origin of UF[3] is changed 24. The programmer preciously recorded all robot points P[n] for a robot task program. However, it is found that during the execution of the robot program, the robot TCP can't always precisely reach to each recorded point. Which of the following statements is correct: (a) The robot has poor accuracy (b) the robot has poor repeatability

With the acceleration shown in the figure below, a particle moves in a straight line motion. Plot the v-t and s-t graphs if the particle’s motion starts from the origin with an initial velocity of −14 ??/?. Also, determine the particle’s maximum value velocity and its position coordinate.

Hello I'm having trouble with this assignment, I don't understand how the plot function works for ordered pairs. I undertand that the points of the line would be the origin(0,0) and (x = cos(theta) . y = sin(theta)).
