can you help me understand how to get the answer and why it works that way. A block of mass 5 kg is on a table, with coefficients of friction of μs=0.50 and μk=0.46. A horizontal force, slowly increasing from zero, is applied until the block is put in motion and then kept constant. What is the acceleration of the block once it starts to move?____m/s2

To understand kinetic and static friction. A block of mass m lies on a horizontal table. The coefficient of static friction between the block and the table is μs. The coefficient of kinetic friction isμk, with μk<μs. Part B Suppose you want to move the block, but you want to push it with the least force possible to get it moving. With what force F must you be pushing the block just before the block begins to move? Part C...

A contestant in a winter sporting event pulls a 42 kg block of ice in the positive horizontal direction with a rope over his shoulders across a frozen lake as shown in the figure. Assume the coefficients of static and kinetic friction are μs=0.1 and μk=0.03. Part (a) Calculate the minimum force F he must exert to get the block sliding in newtons. Part (b) What is its acceleration in m/s2 once it starts to move, if that force is maintained?
Given: a mass (50) kg is on the edge of a rough horizontal
turntable with radius R = 2.00 m Friction coefficients between the
mass and the table are μs = 0.50 and μk = 0.40. The table starts to
rotate (rotate) around the vertical axis of symmetry with a
constant angular acceleration α = 0.60 rad / s2.
It has been asked to calculate the time at which the mass just
will not shift. Can you help me further?
