- (Ch 04 HW Problem 4.90 13 of 2: Consta A 28.0-kg block is connected to an empty 2.12-kg bucket by a cord running over a frictionless pulley. The coefficient of static friction between the table and the block is 0.45 and the coefficient of kinetic friction between the table and the block is 0.30. Sand is gradually added to the bucket until the system just begins to move. Ignore mass of cord. (Figure 1) Part A Calculate the mass of sand added to the bucket.

- If a system is balanced and not moving, the sum of the forces: O depends on the angle of gravity is up, in the y-direction is to the side, in the x-direction is zeroHello, could you please help me with this question. I need second (In what direction must the force (tension) act on the yo-yo?), and third ( What exerts the force?)A block of mass 5,3 kg is connected to a crate of mass m , by a light inextensible string T that is hanging over a frictionless pulley A force of 60N is applied to the block at an angle an of 30° to the horizontal.the block accelarate to the right The magnitude of the kinetic frictional force between the block and the surface is 4,83N . Ignore the mass of the string as well as any rotational effects Apply Newtons second law to each of the objects and calculate the mass m of the crate if the tension T in the string is 80N
- (a) Forces represented completely by 2AB, 3BČ, 4AČ act along the sides of triangle ABC. Find their resultant and the point where its line of action cuts AB and BC. (b) Show that the resultant of forces AB, CB, 2CD and 2AD acting along the corresponding sides of quadrilateral ABCD, is represented completely by 6QP where P divides BD in the ratio 1: 2 and Q bisects AC.With no losses in the string-pulley system, calculate the force.
