A pesky rabbit has been feeding on Mrs. Cromwell’s prized flowers. In order to put an end to this she devised the simple trap below to catch the rabbit. The crate weighs 6.5lb and is supported by stick BC. Find the magnitude and direction of the reaction at A and the compression force in stick BC using (a) the concepts of two and three-force bodies (closed polygon method discussed in chapter 2). (b) Check your answers by doing sum of the forces and moments.

Describe cytokinesis in plants and animals. in animals: in plants.

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
