Every action force has an opposite and equal reaction force. determine which of these are action/reaction pairs. check all that apply. a girl leans against a wall and the wall pushes on the girl. a baseball hits a glove and the glove pushes on the ball. a boy pushes on a door and the door swings open. a soccer player kicks a ball and then another soccer player kicks the same ball. a cat rubs up against a tree and the tree pushes against the cat. a student pushes another student standing in a line, and that student falls into the next student.

The desk has a weight of 75 lb and a center of gravity at g. determine the initial acceleration of a desk when the man applies enough force f to overcome the static friction at a and b. also, find the vertical reactions on each of the two legs at a and at b. the coefficients of static and kinetic friction at a and b are ms = 0.5 and mk = 0.2, respectively

2.22/3.33 points | previous answers tamucolphysmechl1 4.pre.002. ask your teacher my notes question part points submissions used on a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 2.40 m/s. (a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
