ANSWER:-----

FRICTION ANGLE:---- Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. When surfaces in contact move relative to each other, the friction between the two surfaces converts kinetic energy into thermal energy (that is, it converts work to heat).

A retaining wall against a mud slide is to be constructed by placing 1.2 m-high rectangular concrete blocks (ρconcrete = 2700 kg/m3 ) side by side, as shown in Figure 1. The friction coefficient between the ground and the concrete blocks is f = 0.3, and the density of the mud is about 1800 kg/m3 . There is concern that the concrete blocks may slide or tip over the lower left edge as the mud level rises. a) Determine the...

Two masses are on a horizontal, frictionless surface. The plane of the surface is the x-y plane. Mass m1 = 1.0kg is at rest while mass m2 = 2.0kg is moving in the positive x-direction at 15m/s. The two masses then undergo a collision and mass m2 is moving with a speed of 9.0m/s at an angle of 35 degrees after the collision. 1) What is the speed of the center of mass of the two masses before the collision?...

a)An object of mass ?m rests on a horizontal frictionless surface. A constant horizontal force of magnitude ?F is applied to the object. This force produces an acceleration: always only if ?F is larger than the weight of the object only while the object suddenly changes from rest to motion only if ?F is increasing choice A b)Now let there be friction between the surface and the object. If the object has a mass of 10 kg, and ??μs =...
