list the four fundamental forces. give an example of a phenomenon that illustrates two of the forces.

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

Give an example of a collision in real life. use the law of conservation of energy to describe the transfer of momentum. be sure and discuss the momentum before and after the collision occurs. you will need at least 3 sentences to thoroughly answer this question.

Juliette sets the initial velocity to +10 m/s, the acceleration to zero, and clicks “start.” how can shakina describe the subsequent motion of the car juliette controls?
