Q5. The 9-kg ball is connected to a spring with spring constant k = 240 N/m and unstretched length of 0.8 m. Initially the spring is compressed and has length 0.5 m. Then under the constant applied force F= 200 N (in the direction shown in the image) acting on the ball, the spring is stretched to a new length 1.5 m. Determine the work done by weight to the ball during this process. The slope is smooth. 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 1 place after the decimal point, and proper SI unit. Take g = 9.81 m/s². M Your Answer: Answer 40° units F 15°

To be able to use the conservation of energy on a moving body to determine key characteristics about the mechanics of the system. A package of mass m= 1.00 kg is pushed across the surface by a jet of compressed air during an assembly-line process. The package is moved through a distance of s = 47.0 cm. The package and the surface are known to have a coefficient of kinetic friction of μk= 0.15. The package is initially at rest for this process. If the package must be moving at a speed of v = 17.0 cm/s when it has reached the distance of 47.0 cm, determine the average force that the jet of compressed air must supply to the package If it is now desired that the package be at rest when it has reached the distance of 47.0 cm , determine the average force that the jet of compressed air must supply to the package if the package is initially traveling in the s direction at a velocity of v = 13.5 cm/s If the plant has changed the mass of the package on the assembly line to m = 1.35 kg ,…

Consider the mass-on-a-spring system as shown in the figure below. The spring has a spring constant of 1.86e+3 N/m, and the block has a mass of 1.39 kg. There is a constant force of kinetic friction between the mass and the floor of 4.71 N. Starting with the spring compressed by 0.117 m from its equilibrium position, how far will the block travel once it leaves the spring? (Assume that block leaves the spring at the spring's equilibrium position, marked x=0 in the figure. Give your answer as the distance from the equilibrium position to the final position of the block.) Hint: How much work must friction do in order to bring the mass to a stop? How much distance is required for friction to do this work? Enter answer here www.m X = 0 Please enter a numerical answer below.
