1) Accelerating over pulley: Consider the arrangement shown below. The whole system is accelerating. (Assume that the pulley is massless and frictionless. The string is also massless.) (See PSL 5.5,7) Since mass 1 is accelerating upward, choose up as the positive direction for mass 1. Since mass 2 is accelerating downward, choose down as the positive direction for mass 2. This makes the acceleration always positive in all the equations. Avoid lots of sign errors this way. a) Draw FBDs for each mass. b) Use N2L (Newton's 2nd Law) to determine the (i) tension in the string, and (ii) the acceleration. (in terms of m₁, m₂, and g only) m₂

An adventurous archaeologist crosses between two rock cliffs, with a raging river far below, by slowly going hand-over-hand along a rope stretched between the cliffs. He stops to rest at the middle of the rope. The rope will break if the tension in it exceeds 3.00 x 104 N, and our hero’s mass is 81.6 kg. a. If the angle that the rope makes with the cliff is 75o, find the tension in the rope.
15. Which is TRUE when the resultant of all the forces acting on the body is zero? Group of answer choices No answer The body is in equilibrium. The body has a constant velocity. The body has a constantly increasing acceleration. The body is acted upon only by the normal force.
1. A ball of mass m1 and a block of mass m2 are attached by a lightweight cord that passes over a frictionless pulley of negligible mass, as shown in the figure. The block lies on a frictionless incline of angle theta. If theta becomes zero, what will happen? CHOICES: - The acceleration will be reversed in direction. - The velocity of m2 will keep on going. - m1 will start to move upward. - Nothing will change to the acceleration of the system. 2. s = 0.5*a*t^2 is a kinematic equation used to solve acceleration. What can we say about the initial velocity of the body when we use this equation? - The initial velocity is -9.8 m/s. - The initial velocity is 0. - The initial velocity is 9.8 m/s - Cannot be determined. 3. Using kinematics and dynamics equation used in the experiment (newton's second law of motion experiment), derive an expression to solve the time it takes for the heavier mass to reach the ground.

What horizontal force must be applied to a large block of mass M shown in Figure P5.49 so that the tan blocks remain stationary relative to M? Assume all surfaces and the pulley are frictionless. Notice that the force exerted by the string accelerates m2.
4- In the situation below, there is friction between the block of mass m1 and the surface so that μe=0.4μe=0.4 and μc=0.25μc=0.25. The slope of the plane is such that θ=40º c) Assuming that the mass of block 2 is 40 kg and that the mass of block 1 is 10 kg. Under this situation, block 2 descends accelerated and block 1 ascends the accelerated inclined plane, but still under friction, but this time of kinetic nature. Knowing that, according to the above scheme, the acceleration of block 1 has a magnitude 4 times greater than the magnitude of the acceleration of block 2, determine what is the magnitude of the acceleration of each block. Present your calculations d) If the height marked in the figure is 20 m and block 2 starts its movement at rest, determine how long it will take to touch the ground. Present your calculations

A freight train consists of two 8.00×104-kg enginesand 45 cars with average masses of 5.50×104kg . (a) What force must each engine exert backward on the track toaccelerate the train at a rate of 5.00×10–2 m/s2if the force of friction is 7.50×105 N , assuming the engines exertidentical forces? This is not a large frictional force for such amassive system. Rolling friction for trains is small, andconsequently trains are very energy-efficient transportationsystems. (b) What is the force in the coupling between the37th and 38th cars (this is the force each exerts on the other),assuming all cars have the same mass and that friction isevenly distributed among all of the cars and engines?
