Macmillan LearningA half-circle of wire of length L and mass M is placed on acoordinate system such that, if the circle were complete, itscenter would be at the origin. The wire semicircle begins onthe positive x-axis, crosses the positive y-axis at the wire'smidpoint, and ends at the symmetrically located position onthe negative x-axis, as shown.Find the position vector 7CM for the center of mass of thewire in the given coordinate system. Express your answer interms of the given information, using ij unit-vector notation.7CM =

we will find the coordinate of center of mass.

A 1460-kg car is moving westward with a speed of 20.1 m/s, and a 2986-kg truck is traveling east with a speed of 17.5 m/s. Find the velocity of the center of mass of the car-truck system. Assume that the "positive" direction is to the east.

Two blocks of masses M and 3M are on a horizontal and frictionless surface. A massless spring with a spring constant of 96 N / m is attached to one of the blocks. The spring is compressed between the blocks and the blocks are tied with a massless rope as shown in the figure. After the rope holding the masses is cut, the 3M block moves to the right at 2 m / s. In this case, after the rope is cut a) What is the velocity of the block of mass M. b) If M = 0.5 kg, how much was the spring compressed before the rope was cut
IVIT IN UTES ASK YOUR TEACHER PRACTICE ANUTHER A baseball with a mass of 145 g is thrown horizontally with a speed of 39.7 m/s (89 mi/h) at a bat. The ball is in contact with the bat for 1.15 ms and then travels straight back at a speed of 45.6 m/s (102 mi/h). Determine the average force (in N) exerted on the ball by the bat. Neglect the weight of the ball (it is much smaller than the force of the bat) and choose the direction of the incoming ball to be positive. (Indicate the direction with the sign of your answer.)

A system of four buckets forms a square as shown in the figure. Initially, the buckets have different masses (it is not known how these masses are related). A student begins to add water gradually to the bucket located at the origin. As a result, what happens to the coordinates of the center of mass of the system of buckets?(Figure 3). The x coordinate stays the same; the y coordinate increases. The x coordinate stays the same; the y coordinate decreases. The x coordinate increases; the y coordinate stays the same. The x coordinate decreases; the y coordinate stays the same. The x coordinate increases; the y coordinate increases. The x coordinate decreases; the y coordinate decreases. The x coordinate stays the same; the y coordinate stays the same. There is not enough information to answer the question. The third, fourth, seventh and eigth options are incorrect.
Calculate the center of mass of the upper-arm and forearm of a 75 kg athlete using the appropriate anthropometric tables, when we know the position of Marker1 is (3.5,4.5), Marker 2 is (5,3), and Marker3 is (7,4). The upper arm is defined by markers Marker1 to Marker2, whereas the forearm is defined by markers Marke2 to Marker3.
Two blocks, M=8.00 kg and m-2.00 kg are touching and moving across a rough floor (Uk-0.12 at a speed of 4.0 m/s when a force acts on the blocks as shown. The force FO= 68 N directed 52 degrees below the horizontal, as shown. The two blocks are touching so the system can be treated as a single 10.0 kg block which we will call MT. This will apply for questions 13 thru 18.
