depicts the potential energy of a 660-kg pallet that slides from rest down a frictionless roller conveyer ramp, then moves across a frictionless horizontal conveyer, and finally encounters a horizontal spring at x=4.0m. What is the angle of inclination of the conveyer ramp? What will be the speed of the pallet at x=6.0m if it begins sliding from rest at x=0?

As shown in the figure, a 0.490kg object is pushed against a horizontal spring of negligible mass until the spring is compressed a distance x. The force constant of the spring is 450 N/m. When it is released, the object travels along a frictionless, horizontal surface to point A, the bottom of a vertical circular track of radius R = 1.00 m, and continues to move up the track. The speed of the object at the bottom of the track is va = 12.8 m/s and the object experiences an average frictional force of 7.00 N while sliding up the track. (a) What is x? (b)  If the object were to reach the top of the track, what would be it’s speed at that point? (c) Does the object actually reach the top of the track, or does it fall off before reaching the top?

10. A 4.0 kg block is pushed against a spring with negligible mass and force constant k = 700 N/m, compressing it 0.20 m. When the block is released, it moves along a frictionless, horizontal surface and then up a frictionless incline with slope 40°. (a) What is the speed of the block as it slides along the horizontal surface after having left the spring? (b) How far does the block travel up the incline before starting to slide back down? (c) Redo part b. if there is a non-zero coefficient of kinetic friction k = 0.10 on the incline (but not on the horizontal surface). k m 30º

A freight company uses a compressed spring to shoot 1.80 kg packages up a 1.00-m -high frictionless ramp into a truck, as the figure(Figure 1) shows. The spring constant is 321 N/m and the spring is compressed 35.0 cm. What is the speed of the package when it reaches the truck? A careless worker spills his soda on the ramp. This creates a 50.0-cm-long sticky spot with a coefficient of kinetic friction 0.55. How high up the ramp will the package go after crossing the sticky spot?

depicts the potential energy of a 380-kg pallet that slides from rest down a frictionless roller conveyer ramp, then moves across a frictionless horizontal conveyer, and finally encounters a horizontal spring at x=4.0m.When the pallet encounters the spring, it momentarily comes to rest at x=6.0m   At what height h above the horizontal conveyer did the pallet begin sliding from rest?

In the Hunger Games movie (https://openstaxcollege.org/l/21HungGamesclip) , Katniss Everdeen fires a 0.0200-kg arrow from ground level to pierce an apple up on a stage. The spring constant of the bow is 330 N/m and she pulls the arrow back a distance of 0.55 m. The apple on the stage is 5.00 m higher than the launching point of the arrow. At what speed does the arrow (a) leave the bow? (b) strike the apple?

A mass of 25kg is attached to a spring (k=650N/m) and is hung from a ceiling. The mass is released at a height h when the spring is unstretched. a) What is the speed of the mass when it has fallen a distance of 0.30m?  b) What is the minimum release height (h) if the mass does not strike the floor? Both parts answered.
