1.0 kg
The 1.0 kg block in the picture is tied to the wall with a
20 N
rope. It sits on top of a 2.0 kg block. The lower block is
pulled to the right with a tension force of 20 N. The
coefficient of kinetic friction at both the lower and upper
surfaces of the 2.0 kg block is ug = 0.4.
A. What is the tension in the rope attached to the wall?
B. What is the acceleration of the 2.0 kg block?

Consider the pic below. Mass 1 is 1Kg, mass 2 is 2Kg, and mass 3 is 10Kg. The coefficient of kinetic friction on the surface is 0.15. Calculate the magnitude of the acceleration for the system.
MY NOTES ASK YOUR TEACHER A car accelerates down a hill (see figure below), going from rest to 22.0 m/s in 4.60 s. A toy inside the car hangs by a string from the car's ceiling. The ball in the figure represents the toy, of mass 0.200 kg. The acceleration is such that the string remains perpendicular to the ceiling. (a) Determine the angle 0. (b) Determine the tension in the string.
The curved sides of a track where bicycles race (a velodrome) is angled rather steeply. Sketch a cross-section of a bike at some point along this curve, and beside it make the free body diagram of the bike at that moment. Neglect air resistance, and any forces that go perpendicular to the paper (such as those which go in the direction of the bike's motion).

Consider the scenario in the figure below. The mass of block 2 (hanging vertically) is 72.7 kg. The coefficient of static friction between block 1 and the table is 0.250. Find the minimum mass of block 1 (in kg) for which the system will remain at rest. Assume that the mass of the ropes are al negligible. Hint: apply Newton's 2nd law to block 1, block 2, and the knot. Set every acceleration equal to zero, since nothing is moving! m₁ knot m2 41.0⁰
