Setting up purchasing systems that determine standards for each item involves creating

Consider a stationary object placed at rest on a horizontal table. A firecracker explodes inside it and two unequal parts of the original object fly away in opposite directions. If the mass of the lighter chunk is mA  and that of the heavier chunk is mB = 5mA, what is the ratio of their kinetic energies (KB/KA) after the explosion?

Forecasting is used

A 4.8-kg block attached to an ideal spring executes simple harmonic motion on a frictionless horizontal surface. At time t = 0.00 s, the block has a displacement of a velocity of and an acceleration of The force constant (spring constant) of the spring is closest to

Katie is looking to exercise to lose weight. She currently weighs 74 kg and is 163 cm tall. What is her BMI? *Round to one decimal place. Do not include units of measure. 

A 6.52 gram bullet is fired into a 0.601 kg block attached to the end of a 0.670 m non uniform rod of mass 0.698 kg. The block-rod-bullet system then rotates in the plane of the figure, about a fixed axis at A. The rotational inertia of the rod alone about A is 0.0550 kg m2. If the angular speed of the system about A just after impact is 1.96 rad/s, what is the bullet’s speed (in m/s) just before the impact? Treat the block as a particle.

Astronaut Jennifer’s lifeline to her spaceship comes loose and she finds herself stranded, “floating” 100 m from the mothership. She suddenly throws her 2.00-kg wrench at 20 m/s in a direction away from the ship. If she and her spacesuit have a combined mass of 200 kg, how long does it take her to coast back to her spaceship?

Three forces, 1, 2, and 3, all act on an object, as shown in the figure. The magnitudes of the forces are: F1 = 80.0 N, F2 = 60.0 N, and F3 = 40.0 N. The resultant force acting on the object is given by

Estimate the number of times an average person’s heart beats in a lifetime. Assume the average heart rate is and a life span of 75 years.

Consider both Statements. Statement 1 Management seeks to select suppliers primarily for speed, flexibility, and quality when using an efficient supply chain model. Statement 2. The goal of the Newsvendor model is to maximize expected revenue.
