Given the following information, how would you find the acceleration of the two block system? "Two blocks with masses m1 and m2 are connected by a massless string and sliding down a plane inclined at an angle ?, as shown in the figure below. The kinetic coefficient of friction between block m1 and the inclined plane is ?2, and ?3 for block m2. You can assume that the acceleration due to gravity is given as ?."
Consider a pair of masses m1 and m2 connected by a non-stretchable string that runs over a frictionless pulley as shown in the figure on the right. If the coefficient of kinetic friction between m1 and the horizontal surface on which it initially rests is μk, find its resulting acceleration magnitude in terms of m1, m2, and μk, when the system is released. Assume that air resistance is negligible and m2 > μk m1.
A skier slides straight down an incline of 25 degrees without using her poles. The slope itself is 96 meters long, and the skier starts from rest at the top. What would the velocity of the skier be at the bottom of the incline if friction can be neglected? What would your answer be to the previous question if the coefficient of kinetic friction between the skis and the snow is 0.13 on the incline? Upon reaching the bottom of the incline in part b, she reaches a flat portion, and decides to just let friction slow her to a stop. How far does the skier travel along the horizontal portion before coming to a stop, if the coefficient of kinetic friction is 0.28 on the flat portion?
The diagram below shows a block of mass m=2.00kg on a frictionless horizontal surface, as seen from above. Three forces of magnitudes F1=4.00N, F2=6.00N, and F3=8.00N are applied to the block, initially at rest on the surface, at angles shown on the diagram. (Figure 1) In this problem, you will determine the resultant (total) force vector from the combination of the three individual force vectors. All angles should be measured counterclockwise from the positive x axis (i.e., all angles are positive). Part A) Calculate the magnitude of the total resultant force Fr= F1+F2+F3 acting on the mass. Part B) What angle does Fr make with the positive x axis? Part C) What is the magnitude and direction of the mass's acceleration vector, a ? Part D) How far (in meters) will the mass move in 5.0 s? Part E) What is the magnitude of the velocity vector of the block at t=5.0s? Part F) In what direction is the mass moving at time t=5.0s?
Given the following information, how would you find the magnitude of the acceleration of the system. Express youranswer in terms of known quantities such as m1, m2, theta, k, xs, x0, and g. "A ball of mass m1 and block of mass m2 are attached by a lightweight cord that passes over a frictionless pulley of negligible mass, as shown in the figure below. The block lies on a smooth plane inclined at an angle 'theta'. The ball is attached to a spring whose spring constant is k and equilibrium position x0. The spring is then stretched so it measures a length xs. You may use the fact that the force due to a spring is opposite the stretch and equal to −kΔxstretch. The system is then released. You can assume that the acceleration due to gravity is given as g, and use the consistent coordinate system specified for each object."

A block is placed on a flat board that is hinged at one end (pivot). The free side of the board is then lifted very slowly, as shown in Fig. 1(b). When the board is lifted, the friction between the block and the board prevents the block from moving. At a certain angle (θc), at a height h, however, the block begins to slide downward. (a) If the board is held at this angle, with what velocity will the block reach the base? Consider µe and µc as the coefficients of static and kinetic friction, respectively, and give your answer as a function of the variables in the statement. (b) Conceptual discussion - If the condition µc < µe were not true, what would happen to the block and how much would the acceleration be in this situation?
