You have been hired to design a spring-launched roller coaster that will carry two passengers per car. The car goes up a 12-m-high hill, then descends 15 m to the track's lowest point. You've determined that the spring can be compressed a maximum of 2.1 m and that a loaded car will have a maximum mass of 400 kg. For safety reasons, the spring constant should be 12% larger than the minimum needed for the car to just make it over the top. ▾ ▼ Part A What spring constant should you specify?

A small cart of mass 9 kg slides down from the top of a curved track of unknown length. It first passes a small patch of rough surface, and then it hits a spring of rest length 1.61 m and stops. The spring is also located on a second patch of rough surface. if the spring constant of the spring was 18 N/m, it was compressed from 1.61 m to 0.79 m after the cart had finally stopped, and the velocity of the cart when it first entered the second rough patch was 9 m/s, what was the magnitude of negative work done by friction force from the second rough patch in joules? Use g = 9.8 m/s² in your calculations and retain your answer to two decimal places. m h k www d
In the figure, a spring with spring constant k = 180 N/m is at the top of a frictionless incline of angle e = 38°. The lower end of the incline is distance D = 0.92 m from the end of the spring, which is at its relaxed length. A 1.5 kg canister is pushed against the spring until the spring is compressed 0.22 m and released from rest. (a) What is the speed of the canister at the instant the spring returns to its relaxed length (which is when the canister loses contact with the spring)? (b) What is the speed of the canister when it reaches the lower end of the incline?

You are asked to design spring bumpers for the walls of a parking garage. A freely rolling 1100 kg car moving at 0.60 m/s is to compress the spring no more than 7.3×10−2 m before stopping. What should be the force constant of the spring? Assume that the spring has negligible mass
A spring loaded toy dart gun shoots a dart straight up in the air and the dart reaches a maximum height of 22.90 m. The same dart is shot straight up a second time but this time the spring is compressed only half as far. How far up in meters does the dart go this time neglecting friction? Write your answer to 2 decimals. Your Answer: Answer
a cannonball with a mass of 6.95 kg is placed in a vertical, spring-loaded cannon bearing a spring with a spring constant of 5.6 newtons/meter. The spring is compressed by a distance of 4.54 meters and released. Please use g=9.80 m/s2. The max height reached by the cannonball in meters is?

= 2. Refer to the diagram below. A spring-loaded launcher is aimed vertically upward, and compressed 0.13 m beyond its equilibrium position, then locked into place. The spring constant is k 60000 N/m. A block of mass 2 kg is placed on the launcher. When the spring lock is released, the block is launched upward to a maximum height, H. What is this height, H, if the block loses 17 Joules of mechanical energy to air resistance (during its upward flight)? Show all calculations. пиши before launch H = ? риши after launch
