A block of mass M = 2.0 kg accelerates to the right on a surface with a kinetic coefficient of friction of MU_k = 0.30 pulled by a massless string which passes over a massless and frictionless pulley as shown. A block of mass m = 1.0 kg hangs freely from the other end of the string. Call the tension in the string T and the frictional force F_F....

1. Two blocks are connected by a string. Block A is pulled by another string so that it moves across a table with increasing speed. The mass of block A is less than that of block B. Assume that: o the strings are massless and inextensible there is friction between the blocks and the table String 2 String 1 How does the acceleration of block A compare to the acceleration of block B? Discuss both magnitude and direction. Explain a....

3. A block of mass m is held motionless on a frictionless inclined plane by means of a string attached to a vertical wall as shown. (a) Make a free body diagram of the block. (b) Calculate the magnitude of the tension in the string if the mass of the block is 3 kg and angle 0 = 25°. (c) Find the normal force acting on the block.

A large fish hangs from a spring balance supported from the roof of an elevator. If the elevator has an upward acceleration of 2.45 m/s2 and the balance reads 60.0 N , what is the true weight of the fish? SET UP Draw a sketch of the physical situation, and identify the moving object or objects to which you will apply Newton’s 2nd law. Draw a free-body diagram for each chosen object, showing all the forces acting on that object....

Units 13. A 121.65 N sign hangs at rest from a wall and ceiling by massless strings in the configuration show in the figure to the right. The magnitude of the tension in string one is 50 N which makes an angle of 36.87 degrees above the horizontal direction. 8,37 a) Sketch a free body diagram for the sign showing all forces acting on it.

The
mass is 25 grams. Please label and put a box around the
solution.
Purpose: To calculate the apparent weight of a mass when immersed in water. Students will also have the opportunity to learn how to use calipers to accurately measure lenghs. Background: Archimedes discovered that he could find the density of an object by comparing it's weight o its apparent weight when immersed in water (see example 10-8 in he textbook). When mmersed, the buoyancy due to the...

1. A block that weighs 1200 N is suspended as shown from the end of beam AB, which is weightless and is hinged to the wall at A. The beam is 5 m long. The 4 m long cable is attached to point C, which is 3 m from point A along the beam. The cable is perpendicular to the beam a) Draw and label the free-body diagram for the beam, showing all of the forces acting on it. (10...
