A force of 98 N is required to just start moving a body of mass 100 kg over ice. The coefficient of static friction is

A force of 100 gm wt. is required to pull a body weighing 1 kg over ice. The coefficient of friction is

A20 kg block is initally at rest. A 75 N force is required to set the block in motion. After the motion starts, a force of 60 N is required to keep the block moving with constant speed. The coefficient of static friction is

A20 kg block is initally at rest. A 75 N force is required to set the block in motion. After the motion starts, a force of 60 N is required to keep the block moving with constant speed. The coefficient of static friction is

A force of 98N is just able to move a block of mass 20kg on a rough horizontal surface. Calculate the coefficient of friction and the angle of friction.

A force of 98 N is just able to move a block of mass 20 kg on a rough horizontal surface. Calculate the coefficient of friction and the angle of friction (g = 9.8 ms ^(-2)).

A 20 kg block is initially at rest. A 75 N force is required to set the block in motion. After the motion a force of 60 N is applied to keep the block moving with constant speed. The coefficient of static friction is

A force of 98 N is just required to move a mass of 45 kg on a rough horizontal surface. Find the coefficient of friction and angle of friction?
