An 82 kg man on a diving board drops from rest 3.0 m above the surface of the water and he comes to rest 0.55 s after reaching the water. What is the average net force on the diver as he is brought to rest? Remember to first find the velocity of the man after he falls 3.0 m off of the diving board.

You are your friend move a new refrigerator into his kitchen. you apply a horizontal force of 252 n in the negative x direction to try and move the 56 kg refrigerator. the coefficient of static friction is 0.61. (a) how much static frictional force does the floor exert on the refrigerator? give both magnitude (in n) and direction. magnitude n direction (b) what maximum force (in n) do you need to apply before the refrigerator starts to move?
