Consider a 14.5 kg rectangular block of length 0.40 m attached to a spring with aspring constant of 30.5 N/m.The coefficient of static friction between this block and the surface is 0.310. Consider what happens if the block is suddenly disconnected from the spring, asshown below. Choose the correct equation for calculating the coefficient of kineticfriction (Uk.) if it takes time t for the block to travel a displacement of Ax downthe inclined surface. Note that this displacement is negative in the given rotatedcoordinate system, and that the acceleration of the block is constant so the motion isdescribed by the four kinematic equations. Hint: remember thatAx = x – x0 -spring isdisconnected!Дх2 Δηgt cos(0)+ tan (0)2 g t² cos(0)+ tan (0)Hs = cos (0) + sin (0)gt?2 Ax+ sin (0)Ar2 sin (0)I t?- sin (0)2 g t?

A desperate hiker has to think fast to help his friend who has fallen below him. Quickly, he ties a rope to a rock of mass ma and makes his way over the ledge (see the figure). If the coefficient of maximum static friction between the rock and the ground is µ, and the mass of the hiker is mâ, what is the maximum mass of the friend, mc, that the rock can hold so the hikers can then make their way up over the ledge? Assume the rope is parallel to the ground and the point where the rope passes over the ledge is frictionless. mc = Ju
Two blocks of masses m, = 6.0 kg and m2 = 12 kg are connected with a string that passes over a very light pulley (Figure 1). Friction in the pulley can be ignored. Block 1 is resting on a rough table and block 2 is hanging over the edge. The coefficlent of friction between the block 1 and the table is 0.70 (assume static and kinetic friction have the same value). Block 1 is also connected to a spring with a constant 300 N/m. In the initial state, the spring is relaxed as a person is holding block 2, but the string is still taut. When block 2 is released, it moves down for a distance d until it stops (the final state).

a tilted applied force, which requires that we work with components to find a frictional force. The main challenge is to sort out all the components. a force of magnitude F = 12.0 N applied to an 8.00 kg block at a downward angle of u= 30.0. The coefficient of static friction between block and floor is ms = 0.700; the coefficient of kinetic friction is mk = 0.400. Does the block begin to slide or does it remain stationary? What is the magnitude of the frictional force on the block?
Be sure all quantities are expressed in standard units before calculating anything. Thank you :)
I am trying to solve this problem but the equation I came up with dosn't work and I am at a loss with what I might be missing for this so can you please help me?
In the pulley system shown in the figure, one end of a string is connected to the end of a rod, which can rotate about a fixed pin. The length of the string, L, is constant. The rod has a constant length, h, which is equal to the fixed height h in the figure. The other end of the string is attached to a block that can move in the vertical direction. Find the acceleration of block Aa® with respect to a fixed frame. h P
