Need help calculating the minimum magnitude force to start the crate moving A 12-kg crate rests on a horizontal surface and a boy pushes on it with a force that is 30° below the horizontal. If the coefficient of static friction is 0.40, the minimum magnitude force he needs to start the crate moving is: 0 F sin 0 fk 0 F cos 0 F N mg

The coefficient of static friction between the block and the wall is 0.41 and the directional angle 8 for the force is 50.0°. Determine the magnitude of the force (F) when the block is about to slide down the wall.

A 9.0-kg hanging weight is connected by a string over a pulley to a 5.0-kg block sliding on a flat table. If the coefficient of kinetic friction is 0.19, find the normal force on the 5kg block. 5 kg T T 9 kg

18. A child sits on a sled at the top of a hill, the hill makes an angle of 20° with the horizontal. The child's mass is 40kg. Use us = .1 and 4.03 a. b. Draw a free body diagram for this system. Does the child accelerate down the hill? *i.e., check that the coefficient of static friction is vercome by the component of the childs weight in the direction the child would accelerate. If they do, what is their acceleration? *use coefficient of kinetic friction in sum of the forces balance if the child moves.
