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.

A weight is attached to a spring suspended from a beam. At time t = 0, it is pulled down to a point 8 cm above the ground and released. After that, it bounces up and down between its minimum height of 8 cm and a maximum height of 24 cm, and its height h(t) is a sinusoidal function of time t. It first reaches a maximum height 1.4 seconds after starting. (a) Follow the procedure outlined in this section to sketch a rough graph of h(t). Draw at least two complete cycles of the oscillation, indicating where the maxima and minima occur.         (b) What are the mean, amplitude, phase shift and period for this function? (Use a phase shift with an absolute value less than the period.) mean 16   amplitude 8   phase shift      ___   period 2.8   (c) Give four different possible values for the phase shift. (Enter your answers as a comma-separated list.) _______   (d) Write down a formula for the function h(t) in standard sinusoidal form; i.e. as in the…

The complete slide- back and forth motion of a single reciprocating compressor piston completes in a 2-sec period. The volume displacement of the piston though the piston cylinder is 8,902.63 in3. The stiffness of crank is said to be equal to 65.5N/m and the mass of the said piston is at 10kgs. Obtain the following  1. Plot the graph of the following relationship: A) Position vs Time graph B) Velocity vs Time C) Acceleration vs Time

(6 )Suppose you're standing on the ground and throw a frisbee. You want the expression for the acceleration of a point on the edge of a frisbee (flying, rotating disk) in flight relative to yourself. If you know the acceleration of the frisbee's center of mass relative to yourself and the position of your point of interest on the frisbee's edge relative to the frisbee's mass center at a particular instant, what other information would you need? nothing - you have all the information you need the frisbee's angular acceleration the frisbee's angular velocity the frisbee's angular velocity and angular acceleration
