- 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?. A vertical spring with spring constant 250 N/m and whose mass is negligible is loaded with a 0.050 kg ball and it is compressed by 15 cm when "cocked and loaded", then (a) what speed will it give the ball as it just leaves contact with the spring at the spring's equilibrium position and (b) to what height above the original compressed location will the ball reach when it is launched straight up into the air? Include a diagram of the situation.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.
- A collision cart on a flat track is launched using a compressed internal spring. The cart has a mass of 0.5 kg and the spring is compressed 0.03 m. If the spring constant is 270 N/m, how much speed will the cart have when the spring is released? (No friction) O 7 m/s O 5 m/s O 0.5 m/s 0.7 m/sYou have been hired to design a spring-launched roller coaster that will carry two passengers per car. The car goes up a 10-m-high hill, then descends 17 m to the track's lowest point. You've determined that the spring can be compressed a maximum of 2.5 m and that a loaded car will have a maximum mass of 400 kg. For safety reasons, the spring constant should be 13% larger than the minimum needed for the car to just make it over the top. k = 1.4x104 Submit Part B m Previous Answers Correct Correct answer is shown.

It travels 1.0 meter down the incline to a flat surface where it encounters a spring of spring constant, k = 5.0 N/m. (a) What is the car's speed at the bottom of the incline? (b) When the car encounters the spring, by how much does it compress (max) it? (c) The spring is removed and the car now encounters a second incline as shown. What is the maximum distance the car travels up this second incline?

- A mass of 10 kg falls from a height of 1m on a spring and compresses it by 0.25 m. What is the spring constant of the spring?When a chip jumps, the energy comes from the muscles, but also from an elastic protein which is subjected to a compression similar to that of a spring. If a chip, with a mass of 2.0 × 10-7 kg, jumps vertically from a height of 65 mm, and 75% of the energy comes from the elastic protein, determine the initial amount of this energy.8) A cart with a mass of 3.20 kg, an initial speed of 5.15 m/s and an initial height of 4.00 m is moving towards a hill of height 5.00 m, as shown in the figure. On the other side of the hill is a spring with a spring constant of 125 N/m and a height of 2.00 m. (a) Does the trolley reach the spring? (b) If so, what is the maximum compression?
