Oct 20 chapt 5 principles of motor control and movement accuracy. The 2 components of the open-loop control system are: the executive and effector y. Still gmps y has fixed and adaptable components: adaptable solves the novelty problem, fixed solves the storage problem y surface features: time, amplitude, effector. Invariant features characteristics remaining constant when the surface features change: relative timeing, order of components, spatial pattern of movment, distinguish classes of movement (ex. Faster pace all segments speeded up) (define the temporal pattern) When performers change: speed of rapid movement trajectory of movement y y size of the action forces involved y the effector y relative timing is unique to all actions within a movement class (ex. Relative timing throwing y throwing ballistic type activity allowing class of movements y variations: overarm, underhand, sidearm; goal, object size etc. y all share nearly the same relative timing structure (ex.

The vector sum of the individual momenta of all objects constituting the system. In this problem, you will analyze a system composed of two blocks, 1 and 2, of respective masses m1 and m2. To simplify the analysis, we will make several assumptions: The blocks can move in only one dimension, namely, along the x-axis. The masses of the blocks remain constant. The system is closed. At time t, the x components of the velocity and the acceleration of block 1 are denoted by v1(t) and a1(t). Similarly, the x components of the velocity and acceleration of block 2 are denoted by v2(t) and a2(t). In this problem, you will show that the total momentum of the system is not changed by the presence of internal forces.

Part A Find p(t), the x component of the total momentum of the system at time t. Express your answer in terms of m1, m2, v1(t), and v2(t). p(t) =

Part B Find the time derivative dp(t)/dt of the x component of the system's total momentum. Express your answer in terms of a1(t), a2(t), m1, and m2. dp(t)/dt =

In this problem, you will add the three vectors together to get a resultant vector. A student is out walking in New York. She walks 1.00 m to the North then she turns West and walks 11.3 m. Lastly she decides to be adventurous and walk 8.80 m at 48.0 degree South of East. (Use East as positive x and North as positive y)What are the x and y components of vector A her first displacement?What are the x and y components of vector B, her next displacement?What are the x and y components of vector C, her last displacement?What are the x and y components of the resultant vector, her total displacement?What is the magnitude of the resultant vector?What is the angle of the resultant vector with respect to the positive x axis?

A puck is moving on an air hockey table. Relative to an x, y coordinate system at time t = 0 s, the x components of the puck's initial velocity and acceleration are v0x = +3.0 m/s and ax = +8.7 m/s2. The y components of the puck's initial velocity and acceleration are v0y = +9.2 m/s and ay = -1.7 m/s2. Find (a) the magnitude v and (b) the direction ? of the puck's velocity at a time of t = 0.50 s. Specify the direction relative to the +x axis.
