In a laboratory model of cars skidding to a stop, data is collected on blocks sliding across a table as each comes to rest. The stopping distance for each block is measured after it has been launched with some initial speed. Experiments are performed on four blocks, each with mass m = 7 kg. The coefficient of kinetic friction and the initial speed of each block was as follows: a) Block 1: µz = 0.2 , v¿ = 2 m/s b) Block 2: µk = 0.2 , vị = 4 m/s с) Block 3: Иk d) Block 4: µk = 0.4 , vị = 4 m/s Calculate the stopping distance for each block. Note that you can use either energetics (conservation of energy) or kinematics (forces) to answer this question. Try both! 0.4 , vį = 2 m/s

Problems 67. 70. 71. and 72 are grouped. A A block of mass M is placed on a frictionless plane. The plane is inclined at an angle , and the block is a distance d from its end. Of course, we would expect the block to slip down the plane. Suppose we revolve the incline around the vertical axis shown in Figure P6.67 instead. At what period of revolution will the block remain in place on the plane? FIGURE P6.67 Problems 67. 71. and 72.
You push an object, initially at rest, across a frictionless floor with a constant force for a time interval t, resulting in a final speed of v for the object. You then repeat the experiment, but with a force that is twice as large. What time interval is now required to reach the same final speed v? (a) 4 t (b) 2 t (c) t (d) t/2 (e) t/4
On a horizontal air track, a glider of mass m carries a -shaped post. The post supports a small dense sphere, also of mass m, hanging just above the top of the glider on a cord of length L. The glider and sphere are initially at rest with the cord vertical. A constant horizontal force of magnitude F is applied to the glider, moving it through displacement x1; then the force is removed. During the time interval when the force is applied, the sphere moves through a displacement with horizontal component x2. (a) Find the horizontal component of the velocity of the center of mass of the glidersphere system when the force is removed. (b) After the force is removed, the glider continues to move on the track and the sphere swings back and forth, both without friction. Find an expression for the largest angle the cord makes with the vertical.

A 10 kg block with an initial velocity of 10 m/s slides 10 meters across a horizontal surface and comes to rest after sliding for 2 seconds. How much force was acting on the block to make it stop? Your answer should be in units of N but you should only submit the number for your answer (and don't worry about negative signs, just submit a positive value).

In the previous problems, suppose that you are moving the box, and have been moving it at 0.73 m/s. You back away, removing your applied force, and let it slide to a stop. How far does it go without your touching it? (Answer in meters.) The computer generated numbers are now M = 23 kg, μs =0.56, and μk = 0.48.
