A 4.40-kg block is placed on top of a 5.50-kg slab. If the slab is held fixed, the block can be made to slip only if a minimum force of 12.0 N is applied to it. The assembly is now placed on a horizontal, frictionless surface, as shown in the diagram.
a) What is the coefficient of static friction between the block and the slab?
b) What is the maximum horizontal force, F that can be applied to the slab so that the slab and the block will move together without relative slippage?
c) What acceleration of the system results if that force is applied?

Per teacher, there is no friction between the bottom one and the 5.50Kg, but there is friction between the 4.40 kg and the 5.50Kg.

4.40Kg

Force 5.50 Kg

d) Suppose a horizontal force were applied to the block rather than the slab what maximun force that can be applied without producing relative slippage between the block and slab?

e) What acceleration of the system results if that force is applied?

  • Applying Newton's second law

    Between the block and slab, the coefficient of static fraction is 0.60, and 0.40 is the coefficient of kinetic friction. A horizontal force of 100 N is applied to the block (on top of slab).

  • Force and Newton's Laws

    34770 Force and Newton's Laws A 3.5 kg block is put on top of a 6 kg block. To cause the top block to slip on the bottom one, while the bottom one is held fixed, a horizontal force of at least 15.4 N must be applied to the top block.

  • Static Friction and Dual Block System

    The coefficient of static friction between the blocks is the same as the coefficient of static friction between the lower block and the horizontal surface. A horizontal force is applied to the upper block, and its magnitude is slowly increased.

  • Electrostatics and Oscillations: Oscillations in a capacitor

    Try that in the same way. The dielectric slab is placed between the two vertical plates of a parallel plate capacitor. The equilibrium position of the slab and the period of small oscillations is determined.

  • Problem Set

    A constant horizontal force of magnitude F = 10.0 N is applied to the 2.00 kg block, setting it in motion as shown in Figure P4.52a.

  • Static Force

    The only horizontal external force, F, accelerates the whole system, partly to accelerate block m and the rest to accelerate block M. Step 1. "Fnet = m a" applied to the whole object gives: (1) F = (m + M) a Step 2.

  • 3 good questions in mechanics: Force, work and energy.

    Notice that one force is applied directly to the knee, F1, while two other forces, F2 and F3, are applied to the foot. The latter two forces combine to give a force F2 + F3 that is transmitted through the lower leg to the knee.

  • A rectangular slab on a incline - Forces and Number of bolts

    b) Calculate the static frictional force on the slab c) From the above calculation you can see that the slab will slide down the plane. To stabilise the slab, bolts are driven perpendicular to the incline.

  • Block on an Inclined Plane

    A force F is applied to the string and it pulls the block up a frictionless plane that is inclined at an angle theta to the horizontal. Find the force that the string exerts on the block. Please refer to the attachment for complete solution.
