EngDQuestion 8Answer the following questions. Show your work on a separate paper. Round your responses to 3 significant figures. Include appropriate units. Providemagnitude and direction where appropriate.The two boxes below are joined together and are subjected to the force shown until they reach a speed of 10 f/s. The mass of box A is 1 slug. The mass ofbox B is 0.75 slug. Once they reach this maximum speed, the force is removed and the boxes slow down to a stop. The coefficient of kinetic friction0.3. Answer the following questions.between the boxes and the surface is μP = 50 lb2c) How much friction is present as the boxes slow to a stop? Show your work.SolutionIUnitsBDirection2b) Using the Principle of Linear Momentum & Impulse, how long does it take the boxes to stop once the force is removed? Show your work.SolutionUnits

Experiment #2: Acceleration vs. Mass Link https://phet.colorado.edu/sims/html/forces-and-motion-basics/latest/forces-and-motion-basics_en.html In this lab you will determine the relationship between acceleration and mass. Choose an Applied Force at the beginning, and keep it constant for this entire experiment. Set the friction to zero. This will make your Applied Force equal to the net force. Record data for five different values of Mass. Graph Acceleration vs. Mass. Graph this in Google sheets(you want a line graph - it should only have one line). Make sure that Mass information is used as the x value Make sure that Acceleration information is used as the y value Add a trendline – see what fits best – linear, exponential, polynomial, etc … Add a copy of you graph below the table Applied Force (N) Mass (kg) Acceleration (m/s²)

In a rope-climbing competition, all of the lifting is done by the arms; legs can only dangle. Imagine 220-lb Garvin Smith in training, hanging stationary from the rope, his legs off the floor. When prompted by his coach, he rapidly lifts his center of mass by 4 ft. in 0.65 s. Calculate Garvin Smith's acceleration. Round the final answer to one decimal place. Determine the net force (“force imbalance”) producing the acceleration. Round the final answer to one decimal place. Which forces are acting on Smith? (Note that his arms are part of himself, so they cannot exert a force on Smith.) With what magnitude force is Smith pulling down on the rope? Round the final answer to one decimal place. The force of 130.2 lb points _____.
Q3. As shown on the right in image below, the force Facting on the box varies with displacement s, and the coefficient in the image, C = 14. Determine the work done by force Fto the box when the box has displaced s = 1.9 m. Please pay attention: the numbers may change since they are randomized. Negative sign must be included if the work done is negative. Your answer must include 2 places after the decimal point, and proper SI unit. F (N) F 5 3 S 4 C s (m) 1 2
Q2. As shown on the right in image below, the force Facting on the box varies with displacement s, and the coefficient in the image, C = 15.

Let us say that we have a ladder with its own length (L) and its own mass (m) this ladder just so happens to make a (θ) degree angle with a wall. The center of mass of this ladder is 1/3 of the way up from the bottom (it gets narrower towards the top). A person of mass M then decides to climb the ladder until he comes to the halfway point. Wall has no friction but the ground has on the ladder.. a) Draw this situation and label forces so you may set up the statics equations. b) Find the force on the ladder due to the ground (both x and y components) and the force on the ladder due to the wall.
