Please help me solve these problems. Please show all work written out is better. Thank you!

4' Block A, of mass 0.73 kg, is on a frictionless surface tipped at angle 8 = 21" from horizontal and is connected by a light (massiess) string of fixed length that goes around ideal frictionless massless pulley and is attached to block 8. When released from rest, the blocks move in the directions shown with acceleration 0.51 m/s'. (3) Why are the magnitudes of the acceleration of the two blocks equal? Give one reason. (b) Draw carefully labeled free-body diagrams for Block A and block B. All symbols should have a subscript indicating which object they act on. (c) List all Newton's 3'\" law pairs which appear in these free-body diagrams. If there are none, write "none". (d) Are there any forces in these diagrams which are equal due to a reason other than Newton's 3" law. If so list them, otherwise write \"none\". (e) Write an equation which corresponds to applying Newton's second law to the motion of block A, parallel to the surface. This should be symbolic. Take up-hill to be positive. (f) Write an equation which corresponds to applying Newton's second law to the vertical motion of block B. This should be symbolic. Take down to be positive (3) By considering the forces perpendicular to the surface, find the magnitude of the normal force on A. Please give a numerical answer to 2 signicant figures. N: (h) Find the mass of block 8. Please give a numerical answer to 2 significant figures. 1. A skier slides down a steep 27 degree slope. Suppose friction is not negligible: take the coefficient of sliding (kinetic) friction to be p = 0.1. a. Draw the free body diagram: Newton's second law in x-direction (parallel to slope): Newton's second law in y-direction (perpendicular to slope): Relationship between Normal force and sliding friction force: Solve for acceleration: e519
