Two boxes are connected by a massless string across a massless frictionless pulley.  Box S has a mass M and box H has a mass m as shown. a) Do a free-body diagram for these objects. b) Write Newton's Second Law equation for these objects, horizontal component only for box S and vertical component only for box H. c) Solve algebraically for the acceleration of the boxes. d) Given M=8.4 kg and m=5.7 kg, use your equation from part c) to find the value of the acceleration. e) Use this answer to find the tension in the string.

A string, 0.750 m in length, is attached to a hook in the ceiling. A 0.600 kg mass is rotating around the vertical axis and the angle between the vertical axis and the string is 18°. a) Draw the free body diagram and kinetic diagram of the mass. b) Determine the tension in the string. c) Determine the velocity of the mass

A 20 kg box rests on a table. a) What force does the earth exert on the box? Draw a free body diagram and determine b) What force does the box exert on the earth? c) What force does the table exert on the box? d) What force does the box exert on the table?

Also figure 4. A student is holding a barbell as in the question above, but in this case we do not know whether the barbell is moving and we do not know how it might be moving. The Earth is pulling down on the barbell with a force equal to the weight of the barbell. Under these circumstances, which of the following must be equal to the weight of the barbell? Choose all that apply. More than one answer may be correct. The upward force that the hand exerts on the barbell. The upward force that the barbell exerts on the Earth. O None of the other answers must be correct (every one of them could be wrong). O The downward force that the barbell exerts on the hand. 000|

a) Make the following a 'free body diagram' by showing all of the force vectors acting on each of the two blocks. 8 m TOUTE M b) Solve for an equation describing the acceleration of the mass M.

Imagine a box which is on a slanted surface as in the diagram. A cable holds the box in place. The box has a mass of 9.1 kg and the surface makes an angle with the horizontal which is 60 degrees. A) What is the tension? B) What is the normal force acting on the box? C) Without the cable what would be the accleration of the box?

When you stand at rest on the floor, you apply a force on the floor and the floor applies a force on you. A) Draw a free-body diagram of yourself. B) The magnitude of the force the floor applies to you is ____ the force you apply to the floor. Greater than Less than Same as

Set up the free-body diagram and the equations for Newton's 2nd law for each object along each axis. (Note you should have 3 free body diagrams since the rope is not massless. Also note, since the rope is not massless the tension at the top and the tension at the bottom of the rope will not be the same.) F = 200 N 4.00 kg 6.00 kg 5.00 kg

Two masses, m1 and m2 are connected by a frictionless pulley and a massless string (idealpulley system). One mass, m1 sits on a 25o incline that is also frictionless, the other mass issuspended in air, as shown in figure 2. The mass on the incline (m1) has a mass of 5kg. Bothmasses are at rest.a) Draw a free-body diagram for both masses.b) What is the value of m2?
