A mass of 10kg is placed on a horizontal table with coefficient of friction of 0.5 if the mass is static determine weight of the object against the horizontal table,and the limiting frictional force
To determine the weight of the object against the horizontal table when it is static, you need to multiply the mass of the object by the acceleration due to gravity. The acceleration due to gravity is approximately 9.8 m/s².
Weight = mass × acceleration due to gravity
Weight = 10 kg × 9.8 m/s²
Weight = 98 N
Therefore, the weight of the object against the horizontal table is 98 Newtons.
To determine the limiting frictional force, you need to use the equation:
Limiting frictional force = coefficient of friction × normal force
The normal force is the perpendicular force exerted by a surface to support the weight of an object resting on it. In this case, the normal force is equal to the weight of the object.
Normal force = weight = 98 N
Limiting frictional force = 0.5 × 98 N
Limiting frictional force = 49 N
Therefore, the limiting frictional force between the object and the horizontal table is 49 Newtons.
