A block of mass 4.20 kg is pushed up against a wall by a force P that makes an angle of θ = 50.0° angle with the horizontal as shown below. The coefficient of static friction between the block and the wall is 0.300.

(a) Determine the possible values for the magnitude of P that allow the block to remain stationary. (If there is no maximum, enter NONE in that answer blank.)
 |Pmax| =  N |Pmin| =  N

Step 1

(a)

The minimum force exerted on the block to avoid slide and the friction force will acts upwards.

Substitute the values,

Step 2

The maximum force exerted on the block to sliding upwards and the fr...
