I need answer for evaluate #3 Calculate the magnifude of the force if the coefficienf of kinefic fricfion between the blockand floor is 0.20.3. A man pushes a block of mass 20 kg so that it slides atconstant velocity up a ramp that is inclined at 11°.V = k7 of 8Calculate the magnitude of the force parallel to the inclineapplied by the man if a) the incline is frictionless; b) the20 kgcoefficient of kinetic friction between the block and inclineis 0.25.NEWTON'S SECOND LAW:1. A 15 kg load of bricks hangs from one end of a rope that passes oversmall, frictionless pulley. A 28 kg counterweight is to be suspended fromother end of the rope. The system is released from rest. a) draw two freethebodyWhat isdiagrams, one for the load of bricks and one for the counterweight. b)the magnitude of the upward acceleration of the load of bricks? c)the tension in the rope?What is2. Block A has a mass of 4.0 kg , and block B hasa = 2 m/s?Вmass 12.0 kg. The coefficient of kinetic frictionbetween block B and the horizontal surface isHg = 0.250.25. a) What is the mass of block C if block B ismoving to the right and speeding up with anacceleration 2 m/s2? b) what is the tension ineach cord when block B has this acceleration?EVALUATE1. A 25kg wooden plate is held in place by two strings attached to the ceiling and thewall. The string attached to the ceiling makes an angle 40° with the horizontal and thestring attached to the wall makes 90° with the wall. Determine the force in each string.2. A block 4kg in mass rests on a horizontal plane. What value of horizontal force isrequired to (a) move the block, (b) maintain the motion of the block once it is moved?The coefficients of static and kinetic friction are 0.23 and 0.18, respectively. What willthe force be, if the force is instead applied 25° above the horizontal?3. A block has a mass of 6kg and rest initially on a plane inclined at 35°. What value offorce is required to stop the block from sliding if (a) the plane is frictionless, (b) theplane has coefficients of fractions static and kinetic equal to 0.20 and 0.18respectively? What will the value of the force be if the velocity is constant and isdirected upward parallel the incline?4. In the figure, blocks A and B have masses 40 kg and 20 kg,respectively. (a) Detemine the minimum weight of block C tokeep A from sliding. The static and kinetic coefficient offrictions between block A and the table are 0.18 and 0.15,20respectively. (b) What is the acceleration of block A?5. A block of mass 5 kg starts to slide down a frictionlessplane, inclined at 25° as shown in figure 2. The blockmoves from rest at the top.
