You wake up one morning to find yourself in a strange room with opaque walls, and no visible doors or windows. You decide to do some experiments to find out more about your strange situation. Your own body mass is 50.1 kg. You pick up an object and drop it from rest, starting at a height of 1.97 meters above the floor, and it hits the floor 0.380 seconds later. You can ignore air resistance. Based on the outcome of this experiment, when you step on the scale provided for you, what weight will it register for your body? 684 N 911 N 1,367 N 491.5 N
Problem 6: A massless spring (with force constant k = 197 N/m) connects a wall and a block of wood. The system is initially at rest, with the spring unstretched. The block has mass M = 52.2 g and is able to move without friction on a table. A gun is positioned to fire a bullet of mass m = 9.3 g into the block along the spring axis. After the gun is fired, the bullet gets embedded in the block, and the spring is compressed a maximum distance d = 0.81 m. M m
F1 Z Problem 7.65 You are an industrial engineer with a shipping company. As part of the package-handling system, a small box with mass 1.50 kg is placed against a light spring that is compressed 0.280 m. The spring, whose other end is attached to a wall, has force constant k = 48.0 N/m. The spring and box are released from rest, and the box travels along a horizontal surface for which the coefficient of kinetic friction with the box is μ = 0.300. When the box has traveled 0.280 m and the spring has reached its equilibrium length, the box loses contact with the spring. 12.772 ' 2 F2 W S A X command 10 # 3 80 F3 E D C $4 888 F4 R F APR 28 % 5 V T G 6 What is the speed of the box at the instant when it leaves the spring?

When some cars are advertised, they quote a "stopping distance" from some speed to zero. The mass of the car and this value of "some speed" give a measure of initial motion, but we aren't necessarily told the mass. Using the stopping distance, one can directly calculate what physical quantity provided by the brakes? A impulse B chemical potential energy C power D kinetic energy E force F velocity G work H acceleration I mass

g Anderson Video - Work Done by a Spring A block of mass 0.2 kg is launched by a spring k₁= 2.0 N/m as shown below. The block moves along a frictionless horizontal table and pushes another spring, k₂= 2.3 N/m, to the maximum deflection z. If the initial deflection of the spring k, is 0.050 m, what is the maximum deflection of spring k₂? Consider that the masses of the springs are negligible.

A bullet with a mass m, = 12.7 g is fired into a block of wood at velocity v, 253 m/s. The block is attached to a spring that has a spring constant k of 205 N/m. The block and bullet continue to move, compressing the spring by 35.0 cm before the whole system momentarily comes to a stop. Assuming that the surface on which the block is resting is frictionless, determine the mass mw of the wooden block. mw = kg

In the frictionless horizontal plane, the first blocks with masses of m, 2m and 3m, respectively, have a velocity v and the other blocks connected to the spring are in rest. Spring force is not impulsive. Since the spring coefficient is k and the collision coefficient is e, a) How long will the spring be (or shorten)? b) What is the smallest value of the kinetic energy of the system? Hint: The equations can be set up with respect to the moving axis whose origin is at the center of mass of the blocks connected to the spring. m v 2m k 3m
