In warehouses, boxes get lifted up and down a lot, which is usually done by a forklift. A forklift has a maximum load it can handle so you need to know the force acting on the fork. As an example assume that you want to lift two heavy boxes with a forklift. The lower box A has a mass of 150 kg and the upper box B has a mass of 100 kg. Use g = 9.8 ?/?2

a) What is the magnitude of the force (in Newtons) that the forklift exerts on the lower box A while the boxes are moving up at constant speed?

b) What is the magnitude of the force (in Newtons) that the upper box B exerts on the lower box A while the boxes are moving up at constant speed?

c) The forklift has just picked up the boxes off the ground. What is the magnitude of the force that the forklift exerts on box A while the boxes move up and speed up with an upward acceleration of ?=0.5?/?2 ?

d) Assume that the forklift has picked up the boxes from a high shelf and is lowering them to the ground. What is the magnitude of the force the upper box exerts on the lower box while the boxes are slowing down at a rate of ?=0.5?/?2

Determine the intervals on which the graph of ?=?(?) is concave up or concave down, and find the points of inflection. ?(?) = (?^(2) − 17) ?^? Provide intervals in the form (∗,∗). Use the symbol ∞ for infinity, ∪ for combining intervals, and an appropriate type of parenthesis "(", ")", "[", or "]", depending on whether the interval is open or closed. Enter ∅ if the interval is empty. Provide points of inflection as a comma‑separated list of (?,?)...

A buoy bobs up and down, undergo- ing near simple harmonic motion. Which of the following statements are true about the buoy? (a) The buoyancy force is a maximum when the buoy moves the fastest. (b) The buoyancy force is always a maximum when the displacement of the buoy from equilibrium is greatest. (c) The acceleration of the buoy is maximum when it’s speed is zero. (d) The acceleration of the buoy is zero when it’s speed is zero. (e)...

Design a 4-bit up/down counter which displays its output on the the 7-led segment using the decoder used in Lab 2. In this lab, you will design a 4-bit up/down counter which displays its output on the 7-segment LED using the decoder that you designed in Lab 2. The 4-bit up/down counter module has 4 inputs, Clk_1Hz, Reset, Pause, and Up; and a 4-bit output Count. If Reset is 1, the counter should reset its count value to zero (0000)....
