The spring-mounted slider with mass m=100g moves in the horizontal guide with dry friction. The friction coefficient between the slider and the guide is u = 0.05. The two weightless springs together exert a retarding force to the motion of the slider F = -ks, where k = 1 N/m is a spring constant and s is displacement from the equilibrium position. The slider is displaced from its equilibrium position by so=17 cm to the right and released with no initial velocity. Plot the dependence of slider displacements on time. Find the final position of the slider. wwww ○本 wwwww

In order to burgle a local McDonald's, the Hamburglar must climb onto the roof. To do this, a ladder of length 3.31 m and mass 21.2 kg is placed leaning against a vertical wall, as shown in the image below. There is negligible friction between the ladder and the wall, but the same is not true for the ladder and the ground: us ≠ 0 between those two surfaces. Even with that friction, the ladder will start slipping if the angle ø ladder makes relative to the ground is less than 71.0°. Assuming the ladder is uniform (so that its center of gravity is located at its geometric center), what must be the maximum static frictional force (in N) that exists between the bottom of the ladder and the ground? Explain how you solved the problem involving a ladder leaning against a wall. Be sure to state what your known and unknown quantities are, what concepts were applied, and what equations were used!

AI kg mass is rests on a frictionless I meter long ramp and compresses a k = 4000 N/m spring a distance of 5 cm. The ramps angle of incline varies from 10 to 50 degrees, in increments of 10 degrees. For each angle of incline, determine if the block will slide off the top end of the ramp after it is released from the Spring. Output each angle of incline and whether of not the block reaches the top of the ramp.

There is a box with height 1.2 m, width 0.8 m and mass 50 kg. It contains a very expensive equipment, which cannot be tilted while moving. There is a rope connected to the top-right corner of the box that you can pull with. The static friction coefficient  between the floor and the box is 0.4. Assuming the rope angle θ is 30 degrees and  m/s2.   a) Is it possible to move the box using the rope without tilting the box? (need to show details)   b) What is the minimum force required to move the box on the floor?

A piston cylinder device contains B kg of water at A ° C. The frictionless piston with an area of C m2 initially rests on the stoppers and its cylinder volume is 0.03 m3. The pressure in the cylinder must be D kPa for the piston to activate. As the piston moves upwards, when the cylinder volume is 0.075 m3, it touches the linear spring with a spring coefficient of 360 kN/m. Since the final pressure is E MPa, by showing the state change together with the saturation curves on the P-V diagram, a) The water temperature in the last case,b) The work done during the transaction,c) Calculate the total heat transfer. Note: If you think there is missing data, you can choose appropriate values by making the necessary explanations.
